[Part 3] ALSA Speech Compression and FT-857D

This is an update of my previous post

As testing goes on, the .asoundrc file is getting more complexed in its setup. This is where we are up to now, we have 2 profiles going for ‘local’ and ‘DX’ and we select between the profiles by running in terminal

Local:

$ arecord -B 12000 -D local_eq_ -r 44100 -f S16_LE | aplay -B 12000 -D ladcomp

DX:

$ arecord -B 12000 -D dx_eq_ -r 44100 -f S16_LE | aplay -B 12000 -D ladcomp

And now for the dreaded .asoundrc file.

[Part 2] ALSA Speech Compression and FT-857D

This is an update of my prevous post

VK2MEV and myself have been working on better compression and equilisation to use with the FT-857D and our hardware. we have since changed from swh-plugins to the plugin we are currently using is the tap-plugins which seems to do compression and equilisation a lot better that the latter.

ALSA Speech Compression and FT-857D

Well friend and I have been playing around with speech compression as the FT-857D on it own does not have the best DSP. As my friend is keeping a better log of it all and how to set up up on the Raspberry Pi head on over to VK2MEV’s site and check it out.

I have the speech compression running on my computer rather than the raspberry pi at the present moment for testing purposes, but will get around to setting it up on the raspberry pi at later date.

My setup consists of:
Computer
Creative Sound Blaster Play USB Dongle
Heil Pro Set Elite
FT-857D
Necessary cabling to connect between the data port on the FT-857D and the USB dongle and headset
