Frequently Asked Questions
What is the bitrate of standard CD-quality audio?
Standard Red Book CD audio is 44,100 Hz * 16 bits * 2 channels = 1,411.2 kbps (approximately 10.58 MB per minute uncompressed).
What audio bitrate should I use for podcasts?
For spoken voice podcasts, 96 kbps to 128 kbps mono or 128 kbps to 192 kbps stereo AAC/MP3 provides excellent broadcast clarity while keeping file sizes compact.
