[Freetel-codec2] USB interface with codec2

[Faisal Saleem]

Hi all,
I am an engineering student and working on a digital voice project. I am impressed by codec2 and sm1000, the freedv adapter. I just got 2 sm1000 modules and built the firmware sm1000.bin successfully.
My questions are:1) how can i apply codec2 on Recorded voice or Audio file which is stored in USB? My query is how  i access  from USB a Audio file.
how can i do?

Thanks in advance for your precious help  Regards,
Faisal Saleem

Hi all,

Can the Codec2 code be split into two sections?

1) From and to the radio audio. To be put into a dedicated DSP device, see the MMDVM project, Arduino DUE.

2) Human side, microphone and speaker, digital to audio and back, to be done on a full Linux or Windoze system.

A good project for you Faisal Saleem.

Hi Alan,

It would be possible to split the modem end of freedv
(fdmdv,cohpsk,fsk,fmfsk) from the codec end. Currently, however, this is
not really supported by the freedv API (freedv_api.c/.h). If anyone is
interested in doing this for any freedv modes, freedv_api.c and
freedv_api.h are good places to look.

Thanks,

Brady O'Brien

Actually, I think the codecrx() and codectx()/datatx() functions do
exactly what Alan wants.
