Future Download Page for
Mastered 1959 Recording

Placeholder Future - Download Page

This will be the page from which you will be able to download your digital audio file type of choice of the 1959 performance of The Crucifixion by the Annapolis High School (AHS) combined choirs. Those choirs had members from the classes of 1959, 1960 and 1961.

When the digitally mastered version becomes available the beginning of 2023, this will be the first time a mastered version of those performances has existed. More than sixty years after the recording was made, the digitally mastered version will finally sound like it was conceived of by Mr. Kunkle (the choral director) and those who assisted him in creating this recording.

Progress notices, and the Notice of availability the beginning of 2023, will be posted on the home page to apprise you of progress toward the mastered audio files becoming available for download.

The process envisioned for obtaining an audio file download of the mastered recording will be as a simple 2 step process:

  1. The initial step will be to fill out and submit a simple form providing identifying information. (No information you provide will be shared with anyone!) That form will be placed here;
  2. After successfuly submitting that form, you will be presented with the 2nd page of this process containing buttons from which you will be able to click on your prefered audio file format to obtain a download of a digital audio file of the mastered recording.

(Those pages for that 2-step process will be added here later this year and activated the beginning of 2023 when The Crucifixion becomes public domain in the U.S.)

When you click on your selected audio file format, it will be downloaded to the Downloads folder on your computer (unless you have changed your browser's default setting for how your browser handles file downloads). If you have not changed your browser's default settings for file downloads, your browser will save it to the Downloads folder and leave it to you to move that file from the Downloads folder on your computer to wherever on your system, or any other media, where you want the file to reside. You can also rename it, if you wish.

Cautionary NOTE. The Downloads folder is typically on your "C" drive. If your "C" drive is almost full, the download could fail if there is not enough room for the audio file. In such a case, one solution is to change your Browser's download default for where it saves downloaded files to direct the save location for file downloads to another drive on your system with more available storage space. (See explanation how to do so inside the below window.)

NOTE. It appears the default location adopted by all browsers for where they save a downloaded file has become the Downloads folder on your computer's "C" drive. Thus, unless you have changed the default settings of your browser for where it saves downloaded files, your browser now automatically saves downloaded files in your Downloads folder.

Thus, when you click on one of the buttons on this page to download a digital file of this mastered recording, you will not get any dialogue about where to save it. Instead, your selected file format will automatically be saved to your Downloads folder on your "C" drive. There are slight variations among browsers. Here are examples of three:

  1. The current Firefox browser default setting is to automatically save the file to the Downloads folder on your computer with the same name of file as on the server. In this case the file name will be The Crucifixion.

  2. The current Edge browser does the same, automatically saving the file to the Downloads folder on your computer with the server's file name, which will be The Crucifixion.

  3. The current Safari browser for the Iphone (and Ipad) is slightly different. It gives you the choice whether you want to "view" or download. (The term "view" in this case, since it is a sound audio file, presumably means listen to the file.) When you select download, Safari also automatically saves the file to the Downloads folder on your Iphone (Ipad) with the name from the server, which will be The Crucifixion.

NOTE. You can change your browser's default file download settings to another folder/drive. (In some browsers the options for changing how downloads are handled may be under advance settings.) You can:

What Audio File Encoding Format to Choose?

There are a variety of audio file encoding formats. An old popular commonly known standby is MP3. That file format became the most popular because of the compressed small file size, back when that was more important. However, it is a lossy compression that decreases the audio quality. If you want to preserve the audio quality available on the 1959 record, that means you should select one of the better audio fidelity file formats. While TortoiseClimbing™ will offer an MP3 option, it recommends considering instead choosing one of the 3 better audio quality file formats to download for your copy of The Crucifixion.

If you are not familar with currently available audio file formats, the following window provides a discussion of facts about audio file encoding formats to assist you in making your choice of which file format you may wish to download. For best audio fidelity in a lossless, but somewhat compressed file format, you might want to choose the FLAC format as a best compromise, or the comparable ALAC for Apple products.

If you are not familar with differences between the popular compressed digital audio file sharing formats of FLAC, ALAC, AAC and MP3, plus uncompressed high resolution audio file formats, such as WAV and AIFF commonly used by recording studios, here is some background.

MP3 is the oldest and worst audio quality format. It was released the end of 1991, at that time as a registered product requiring copyright royalties. (As of 2017 all copyrights associated with MP3 were expired, and subsequently all attemptes to enforce royalties have been dropped.) This compressed file format met 2 goals:

  1. The need for storing much smaller music files on limited, expensive memory devices; and
  2. The ability to more quickly transmit much smaller files, initially over phone lines using ISDN, but later over the early limited bandwidth of the internet, which initially used dialup modems on phone lines.

MP3 creatively uses lossy data-compression to compress data using approximations and partial discarding of data. A major portion of its compression works by eliminating certain components of sound considered (by psychoacoustic analysis at that time) to be beyond the hearing capabilities of most humans. It is commonly referred to as perceptual coding or as psychoacoustic modeling. The remaining audio information is then recorded in a space-efficient manner, using MDCT and FFT algorithms.

Smaller file size is the strength of MP3 compared to CD-quality digital audio. MP3 compression can commonly achieve an impressive 75 to 95% reduction in file size. The combination of small file size and "acceptable" audio fidelity to many, eventually led to a boom in distribution of music over the Internet. That began in the mid-1990's and blossomed in the late-1990s. MP3 served as the major enabling technology for music file sharing at a time when bandwidth and storage were at a premium. The MP3 format initially gained near-universal hardware and software support primarily because it was the first functional compressed audio file format during the crucial first few years of widespread music file-sharing/distribution over the internet.

Saying MP3 generally eliminates pieces of the recording unheard by the human ear is a bit of an oversimplification. However, the fact is that any compression that discards part of the original information does have an impact on the final recording, i.e. a CD-quality song compressed into an MP3 format will sound different. Typically, cymbals, reverb and guitars are the sounds most affected by MP3 compression and can sound really distorted or "crunchy" when too much compression is applied. Like a CD, MP3 files are limited to a 16 bit depth, and a sampling rate of 44.1 MHz. Although MP3 is the worst audio quality, it is supported by virtually all devices.

AAC (Advanced Audio Coding) is a better audio quality lossy file compression format. It was created as a better successor to MP3, with better audio quality at even lower file sizes. Like MP3, it too is a lossy compressed file format. It was designed to be the successor of MP3 format and was first declared a standard in 1997. Blind tests in the late 1990s showed AAC demonstrated greater sound quality and transparency than MP3 for files coded at the same bit rate.

AAC is now a strong contender to MP3 due to some unwavering industry support. In 2003 Apple switched from MP3 and adopted AAC as the standard compressed audio file format in Apple’s iTunes and iPods. It produces better audio fidelity at the same very small audio file sizes associated with MP3.

Most new smartphones and music-themed phones support playback of both AAC and MP3. (Note. AAC is not supported by current HTML5 for the web player control.) If you are restricted to a small file storage area and thus need a more significantly compressed file format than provided by FLAC or ALAC, you probably should consider AAC as your first choice because of its superior sonic performance over MP3. If for some reason your system cannot play the AAC audio file format, you can always delete that file, if you need to free up the space, and come back and repeat the download request process and download the MP3 version.

FLAC (Free Lossless Audio Codec) is an open music format for lossless audio file compression. It has always been provided under royalty-free licensing. It was created about a decade later than MP3, WAV and AIFF when:

In that environment, for purposes of storing and transmitting audio files, it was still important to make audio files smaller than CD size, but the desire to have a compression methodology that also preserves the original sonic quality had become important enough that a digital encoding format meeting that requirement was needed.

Thus, while FLAC is a compressed format, it doesn’t sacrifice any detail from the original recording. In contrast to MP3 and AAC, it is a lossless compression file format. That means no audio data is discarded during the compression process. While this results in larger files than MP3 or AAC compression, they are still 50 to 70% smaller than a CD audio file, and it meets the requirement that no audio details are missing from the files you’re hearing.  (A FLAC file can be converted to an MP3, but not the reverse.)

Now days:

Because FLAC is a lossless compression technology, it is suitable as an archive format for owners of CDs and other media who wish to preserve their audio collections. If the original media are lost, damaged, or worn out, a FLAC copy of the record in this case, or any other audio tracks, ensures an exact duplicate of the original data can be recovered at any time.

TortoiseClimbing's'™ preference is to preserve all the sound quality on the original record pressed from the AHS combined choirs’ performances in 1959. (The same audio quality could be achieved with WAV or AIFF, but the file size would be significantly larger.)

Audio purists are drawn to FLAC because it is both a smaller file size than WAV, and it leaves the sonic qualities of the recording untouched. Additionally, FLAC supports a range of bit depths and sampling rates that go high enough to satisfy all high resolution desires.

NOTE. Audio files processed at Slipped Disc routinely use a bit depth of 24 bits, and a sampling rate of 88.2 MHz.

NOTE. FLAC files can be played on Apple products, but it requires a 3rd party player. Such players are readily available for download and installation.

ALAC (Apple Lossless Audio Codec). Apple does not support easy use of the FLAC lossless audio file format. It only natively supports their Apple Lossless Audio Codec (ALAC) format for lossless digital music encoding on their products. For the benefit of those who are Apple users, TortoiseClimbing™ will include the ALAC format for Apple devices.

Note. However, Apple's current native support for the ALAC audio file format only goes up to a 24 bit depth at 48 Mhz sampling rate. Higher sampling rates, like 88.2 Mhz require a 3rd party player, which can also play the planned FLAC file.

Thus, TortoiseClimbing's™ ALAC audio file will be at 24 bit 48 Mhz. The higher resolution FLAC audio file format will be available that can be used for Apple products, but will require a FLAC player. Such players are available in the Apple Apps store.

AIFF (Audio Interchange File Format). Apple developed its own uncompressed digital audio file format called AIFF for the Macintosh computer in 1988, allowing full studio-quality audio recording and playback on Apple computers. Thus, it is commonly used on Apple Macintosh systems.

The dominant Digital Audio Workstation (DAW) Pro Tools, widely used by recording studios, can work equally well with audio files in either WAV or AIFF format. Thus, Pro Tools is equally at home on Mac or Windows computers in recording studios.


WAV (Waveform Audio File). This file format for digitally encoding audio was subsequently created by a partnership between Microsoft Windows and IBM in 1992, so high resolution WAV audio files could play back natively on Windows computers. (At that time the operating system was Windows 3.1, which was replaced by the very successful Windows 95 in 1995.) (IBM was involved because they were still working with their operating system for PCs known as OS/2.)

WAV is deliberately a high resolution digital encoding file format, and results in very large file sizes. It can encode much higher fidelity material than is possible on a CD. It is widely used internally within portions of the recording industry for sharing working files between Windows based computers during the process of creating a recording. While it could be used for presenting final recordings, its very large file size has thus far discouraged that use.

The Result. Today, even though there are other audio encoding formats in addition to these, almost every record label is on board with providing the audio files they sell in the FLAC file format. As a result, consumers can buy FLAC encoded lossless audio files from both major and indie acts for the same price as tunes from the iTunes Store. (Although since iOS 11, iPhones have supported an indirect version of FLAC playback, Apple does not natively support FLAC or sell FLAC encoded files from the iTunes store. None of Apple's products, MAC included, natively support playing FLAC files.

However, readily available 3rd party players enable all Apple products to play FLAC audio files, i.e., the players can also be used on iPhones. The easiest way to play FLAC files on an Apple product is by using a 3rd party player. There are a number of suppliers. For more information see 10 Best Music Players for Mac users (January 2022).

Plus, Apple has announced they are now supporting their version of lossless compressed music files, called Apple Lossless Audio Codec (ALAC). But, current Apple products do not natively support higher resolution ALAC audio files than 24 bit depth at 48 Mhz. However, that is still considerably better than the lossy compression provided by MP3.

Most Windows devices as well as Android operating systems will play FLAC audio encoded files natively without any additional 3rd party software.

Many think of the iPod, introduced in October 2001, as popularly introducing the concept of a Digital Audio Player (DAP), and it initially used the MP3 digital audio file format. (However, in April 2003 Apple migrated to using AAC after they developed that audio file format as a better alternative to MP3.) Apple announced (in 2022) it is discontinuing manufacture of iPods, but there are a number of other DAPs available on the market for playing high resolution digital audio files.

So, 50 years ago you might have had a turntable to play LPs, or 40 years ago a CD player. (Note. The LP is undergoing a growing renaissance.) Now, you can get a DAP (Digital Audio Player) to play multiple varieties of digital format audio files. FLAC is one of the popular digital file formats for such high resolution players. DAP's come in small portable versions, like the iPod did, to slightly larger. (They are all relatively small.) They can drive headphones directly, or you can plug them into your sound system. There are numerous articles evaluating available DAP players, such as 15 Best Hi Res Audio & HD Music Player's for Audiophile's (March 2022)

As an audio file format, FLAC may never be as popular a format as CD and DVD were in their heydays, but it's quickly become an audio file format of choice for a number of people who care about sound quality.

TortoiseClimbing's™ Plans

TortiseClimbing's™ anticipated digital audio files and the resolutions that will be provided are the following:

Advance "Guestimate" approximations for file sizes of the mastered audio file for the album are:

Form for Future download will be here.

The 2 step process envisioned for obtaining a download of the mastered recording is the following:

First. A simple form will ask you for several easy pieces of information. The simple form will consist of something like the following:

  1. Basic Identification - To understand who is interested in this recording, some basic information will be requested, such as:

  2. CAPTCHA Code - Required. To prevent internet robots (bots) from successfully submitting requests for downloads, the identification form will present an image of a CAPTCHA code and ask you to input what you see.

Second. After you successfully submit the simple information form, you will be presented with a second page containing the 4 buttons representing the choices of audio file formats available for download. Click on the button for your selected audio file format your wish to download.

As noted above, preliminary thoughts are to make the mastered recording available in FLAC, ALAC(??), AAC and MP3 audio file formats. Thus, 3 known different download buttons (and possibly a 4th) that might look something like the following will be included on the second page of this download process. Click on the button for the audio file format you wish to download:

Lossless audio file formats - Best audio quality

24 bit, 88.2 Mhz

ALAC(??) - Apple
 24 bit, 48 Mhz

Lossy audio file formats - Smaller file size, but less audio quality

  AAC - Apple
24 bit, 44.1 Mhz

  MP3 - All
16 bit, 44.1 Mhz

- poorest audio quality

Clicking on any of these buttons will download the selected digitally mastered audio file of the 1959 AHS recording of The Crucifixion in the file format you clicked on, to the Downloads folder on your computer (unless you've changed your Browser's download location.)


During the interium, pending completion of the digital mastering process later this year and beginning of availability for downloading the beginning of 2023, this page provides a placeholder example of another audio control. This control is used for playing an MP3 clip of music on this webpage (streaming).

In contrast to the lack of interactiveness of the download functionality discussed above, which is basically a batch file download to your computer, the streaming Audio play control allows you to start and stop the streaming of play, and adjust the sound level for playing the song.

Clicking on the audio control below will play a preliminary draft of an mp3 file format for the closing number from the Hymns and Songs for Living album being produced by TortoiseClimbing™. The example sound file played is a rough draft of "God Be with You Till We Meet Again."

Listen to "God Be With You Till We Meet Again":

Audio controls like this may be used for presenting streaming MP3 previews on this webpage of pieces from the mastered The Crucifixion recording.
