Hi Alan
Yes, happily working my way through stock of wine - including Australian :-)
Sent a little more info in the other message. If I try the 2020 LPCNet test (cat wia.wav | lpcnet_enc | ofdm_mod | ofdm_demod | lpcnet_dec | aplay) it runs and the audio sounds good but with a few underruns. If I split it ( cat wia.wav | lpcnet_enc | ofdm_mod > file ) takes 35%, and then the rest (ofdm_demod | lpcnet_dec | aplay) took 65 (ish I think from memory).
Compiling codec2 with LPCNet extensions for 2020 is pretty straightforward - I put a copy on the WARC website on the smalldv page.
At this end, Dave 'BCU is playing with the hardware, I'm doing the software.
