How about ability to set the clock? The bit rate for WAVs is decided by the number of bits per sample, the number of channels and the sample rate. At 44100 Hz sample rate, stereo and 16 bit samples, the bit rate is 1411 kbps, which is AFAIK the only bit rate Rockbox has been capable of recording since recording was included. Right now there's also an option to record mono files, which would halve the bit rate. Also, as far as I know, you really don't have a choice now either. The only WAV quality option I can find is the full quality one. As for recording in more compact formats, we currently support MP3, which as you probably know is lossy, and Wavpack (WV) which is a lossless format. Ogg Vorbis will probably not be supported for a good while thanks to seeming to need a more powerful CPU than we have in what targets we currently support. What do you mean about setting the clock? Sample rate? If so, this is something you can expect seeing in the not too distant future.
