Hi, Does audio files have codec formats? I simply convert all my audios (MOH, accouncements) to .wav format, 16bit, 11kHz (I believe this is the best format for asterisk). I am new to this and may be incorrect.
Going forward, (a) How can I check the codec format of my announcements, MOH ? (b) How can I record/convert announcements, MoH etc to a particular format ? I believe its a good idea to prevent transcoding and save CPU overheads.
