Auditec, Inc. is proud to be a small business with a long history. We have been serving professionals with auditory test materials in a variety of formats since 1972.
Long before the Sony Walkman was invented, Auditec sold its auditory test recordings on reels.
Next, Auditec sold auditory test materials on cassette tapes. Believe it or not, we still get requests for this discontinued format. At one point in time, Auditec even made its recordings available on digital audio tapes (DATs).
Now, Auditec provides quality audio recordings on compact discs. Customers can combine multiple recordings to one disc and play it using their CD player or computer.
MP3s are a convenient next step for professionals who want to use portable equipment that does not take up a lot of space like iPods, iPads, and MP3 players. (This article was edited on March 23, 2017 to include recent research by Jennifer M. Brace and Robert W. Keith.) Recent research has concluded normal listeners tested using the mp3 audio files of speech discrimination tests produce the same valid results as when tested using the wav audio files on compact discs.
