a lower bit rate? #53

Closed moseranliunian closed 1 year ago

moseranliunian commented 1 year ago

How should I modify to achieve a lower bit rate? I think your lowest bit rate is 1733? I would appreciate it if you could share your solution

Study the examples in the README, e.g. https://github.com/drowe67/LPCNet#fully-quantised-encoderdecoder-programs

Maybe I'm a little stupid and can't understand how to achieve it all. Could you explain more ?

tmiw commented 1 year ago

Looks like the decimate option in lpcnet_enc and lpcnet_dec would be what controls that if I'm understanding the current docs correctly.

Anyway, this should probably be continued in the Discussions section but it doesn't look like that's there right now. @drowe67, can that section be added or should we just use codec2's?
