Audio File Formats

Deep Mind produces and sells audio in various formats to suit your needs. Some formats can only be played on certain devices unless the files are converted into another format by the customer. It is possible to convert audio files from one format to another but normally specialised software is required for this.

If you have purchased a CD in the past (please note that as from December 19, 2012 we no longer offer the option of purchasing physical CDs) you have the option of playing your CD on a CD player or ripping the files from the CD to the hard drive of your computer. Once the files are ripped, you can either play them through the audio system of your computer or transfer them to a portable audio playback device like an iPod, iPhone, or MP3 player.

Because the downloadable files we offer are pre-formatted to play on popular audio devices, this allows customers the convenience of simply transferring the files to their portable device.

In early 2012, Deep Mind undertook a survey of customers to determine the audio file types that people preferred to download. As a result of this survey we offer three compressed downloadable file types to play on different devices. These are shown in the table below.

MPEG-1 Audio Layer 3 files, commonly abbreviated to MP3 files, are considered “lossy” because during the process of compression (to create smaller files for download), some audio quality is lost. We also offer Free Lossless Audio Codec (FLAC) and MPEG 4 Audio (Apple Lossless; M4A) files, which, as their name implies, are both lossless formats. Lossless compression makes the file smaller without any loss in quality whatsoever, which makes it perfect for downloading brainwave entrainment audio. Our MP3 files are generated from our high quality master audio files and are provided at 320 kbps, which is indistinguishable from CD quality. The quality of our downloadable lossless files surpass CD quality.

You can see in the table that M4A (Apple Lossless) files can be played on various Apple devices including the iPod, iPhone, and iPad. M4A files can also be played on your PC or MAC using iTunes. The one exception here is the iPod Shuffle. At the time of writing, the iPod Shuffle still does not support lossless M4A playback.

MP3 files are very popular and are supported by a multitude of devices including dedicated MP3 players and mobile phones. They can even be imported into iTunes and either played there or converted to other file types that can be played on the Apple range of devices. The downside of MP3 files is that during the compression phase, some audio quality is lost.

If you would like to convert your files to other file formats, we recommend Freemake Audio Converter software. This software is easy to use and is completely free. You can use Freemake Audio Converter to convert your lossless FLAC or M4A files to MP3, WMA, AAC, or OGG files. You can even convert your FLAC or M4A files back to WAV files without any loss in quality for burning to a CD if you wish. See downloadable resources at the bottom of this page that shows how to use Freemake Audio Converter.

Please note: Your license that comes with your purchase allows you to rip the files from your CD (if you purchased this option) for your own use. You can also convert them to another audio type for playback on your preferred audio device. However, you cannot share these files or break them up and modify the content. Please respect the license that you have purchased.
