setvolume(byte newvolume) - sets the volume (both left and right to same value).setboost(...) - sets the audio boost enhancement.
setboost(bass_amp [0 - 15], bass_freq [0 - 15], treble_amp [-8 - +7], treble_freq [0 - 15])
I've been playing with it a bit, plugged to 2 small 8ohm speakers in series (to match the 16 ohm output impedance, and my sound file is mono): the output sound is very low, especially for bass.Before thinking about how to add an amplifier, I wanted to try the volume and boost settings of the rMP3.
In a more general perspective, I trust in rMP3 as a very useful and handy device (I bought 3 for my project), but now that it is fully compatible, is it not time for a synthesized documentation, in a single, linear document ? I know everybody's busy, but I have the feeling that at the present moment, important bits of info are spread over in the rogue wiki, which can be an obstacle for "base" users like me.
Am I missing something ? what do you mean by "This depends completely on the speakers" ?
