If there is a question you do not find an answer to, please notify one of the developers or ask the question in, e.g., the [HydrogenAudio](https://www.hydrogenaud.io) forum. + ### How does the bit-rate mode of the exhale application work? -TODO +As documented by the exhale application when running it without any arguments on a command-line (see the [README.md](https://gitlab.com/ecodis/exhale/blob/master/README.md) file), the bit-rate mode is a number `#` between 1 and 9, where a higher number means a higher constrained variable bit-rate (CVBR) configuration of the exhale encoder library. The resulting bit-rate when encoding a particular audio file with a specific CVBR mode depends on the CVBR mode as well as the content of the audio file (signal characteristics, sampling rate, and channel count). On average, the following mean (and minimum/maximum) bit-rates are obtained for the given mode: + +| Bit-Rate mode `#` | Mono Audio, 1 Channel | Stereo Audio, 2 Channels | +| ----------------- | ---------------------- | ------------------------- | +| 1 | **32** (26/38) kbit/s | **64** (48/80) kbit/s | +| 2 | **40** (32/48) kbit/s | **80** (64/96) kbit/s | +| 3 | **48** (38/58) kbit/s | **96** (76/116) kbit/s | +| 4 | **56** (45/67) kbit/s | **112** (90/123) kbit/s | +| 5 | **64** (51/77) kbit/s | **128** (102/154) kbit/s | +| 6 | **72** (58/86) kbit/s | **144** (116/172) kbit/s | +| 7 | **80** (64/96) kbit/s | **160** (128/192) kbit/s | +| 9 | **96** (77/115) kbit/s | **192** (144/230) kbit/s | ### I get corrupted files when encoding using exhale via foobar2000.
