Best Audio Possible

Would anyone happen to know if there is a program that records or transcode, wave audio files into the trixbox Linear sound format other than using trixbox. I’m not a programmer . Like everyone, else I’m trying to achieve the best audio possible
currently I’m using, Nuendo, soundforge, wavelab, sorenson squeez, and audacity for audio production and know my way around these programs very well.

Also would anyone happen to know how to raise the caller side audio volume.
When I call to test the IVR menu for audio quality the volume is very low.
I 've read quite a few post and because trixbox is so well thought out and packed with features I find it hard to believe there is no obvious way of doing this from the UI " user Interface". Well mabe in future versions of TB just for nonprogramers like me.

Thanks for the help.
