WAV files, AIFF, MP2, MP3, RealMedia...there are many possible formats for sound files. What format should you use for your production material and for your master sound file (the original, electronic file that you will keep on your system)? To get the highest possible audio quality for production and mastering purposes, use a non-data-reduced format, such as linear PCM (pulse code modulation), BWAV, WAV, AIFF, or SD2.
Note: Transcoding (converting your sound files from one format to another) degrades audio quality. Multiple transcodings (converting your master file from one format to another and then converting the newly encoded file to still another format) degrades audio quality further. Always begin with your non-data-reduced master sound file when encoding. Remember, additional transcodings may occur after you upload the file to the ContentDepot for delivery, as the program wends its way through the stations' broadcast facilities.
