Okay, on the dev branch I now documented the -L option (bitrate cap for VBR encoding) and also "unlocked" arbitrary bitrate caps.
This might be interesting for, e.g., low-bitrate internet radio stations that don't dare using unrestricted VBR encoding.
For example, I find that this gives "bearable, radio-esque" quality:
hmp3 -F16000 -V0 -T-28 -L64 test.wav test.mp3
ca. 85-90 kbps VBR encoding, with a VBR bitrate limit of 128 kbps (64 per channel)
Fun can be had by specifying "waaay too low" bitrate caps.
