What bitrate should I use for MP3?
The average bitrate for an MP3 file is 128 kbits per second or kbps. A file created at this bitrate should have good quality and takes up about 1 Megabytes of data per minute of audio.
How do I know if my MP3 is VBR?
In CBR files, all frames use the same bitrate and therefore every header has the same bitrate information. To detect if a file uses VBR, you have to go through every frame of the file, look at the header and check if the bitrate field changes. If it does, its an VBR MP3.
What bit depth is MP3?
Bit Rates for MP3 files range from 16 kilobytes per second (kbps) to 320 kbps. A Sample Rate of 44100 Hz and a Bit Depth of 16/Bit Rate of about 320 kbps is known as the Red Book standard for audio CDs. Here is a comparison of lossless and lossy files with their associated quality vs size.
