About Our MP3s

MP3 Logo imageMP3 is currently the most popular and widespread compression format for audio files. Audio is compressed for use on the internet in order to make file sizes smaller and download times acceptable to consumers. The MP3 format is hugely popular and accounts for the vast majority of audio downloads from the internet.

Our MP3 sound files are made from uncompressed CD-quality (or better) master recordings. We use a high MP3 constant bitrate (CBR) compression of 256kbps (kilobits per second) in order to minimize compression artifacts (this is the same bitrate used by Apple iTunes and Amazon MP3). Experts agree that recordings compressed at 256kbps CBR are extremely high fidelity, convey the full frequency range, and sound nearly identical to the originals – yet they are only one-fifth the size of their uncompressed counterparts!
