With audio, music is the deciding factor. If your video is voice-only, you most likely could lower your sample rate to 22kHz, while music would be better at 32 or 44.1kHz. Lowering the bit rate can make your file smaller as well. Bit rate, or the number of bits per second of video, changes quality with different codecs. If you are using MP3 compression at 192kbps. your music will sound quite good. As far as music is concerned. 96kbps is low quality, and 320kbps is generally considered to sound exceptional. Again, this changes with the type of compression used, so you may want to experiment.
