Audio bit rate

What is audio bit rate

Audio bit rate is a measure of the rate of information content in audio stream. It is quantified using the bit per second (bit/s or bps) unit or Megabits per second (Mbit/s). In the same compression way, a higher bit rate allows better audio quality.

How to choose best audio bit rate

To choose the best audio bit rate for the output file, you have to consider the player. Different players have different sound quality with the same audio bit rate. Also, you have no way to get better audio quality than input file. If you want to keep the same sound quality of the input file, you can choose the original in audio bit rate option.

Bitrates in Audio

32 kbit/s – MW (AM) quality
96 kbit/s – FM quality
128–160 kbit/s – Standard Bitrate quality; difference can sometimes be obvious (e.g. lack of low frequency quality and high frequency swashy effects)
192 kbit/s - DAB (Digital Audio Broadcasting) quality
224–320 kbit/s - VBR to highest MP3 quality
800 bit/s - minimum necessary for recognizable speech (using special-purpose FS-1015 speech codecs)
8 kbit/s - telephone quality (using speech codecs)
32-500 kbit/s - lossy audio as used in Ogg Vorbis
500 kbit/s–1,411kbit/s - lossless audio as used in formats such as Free Lossless Audio Codec, WavPack or Monkey's Audio
1,411.2 kbit/s - PCM sound format of Compact Disc Digital Audio
