Frodigi 2 - Free Running Oscillator Digi 2
An update to the encoder which now has the following additional functionality..
12bits frequency per waveform (normalised to $0000-$0fff)
multiple amplitude level encoding (via silent channels)
25hz update mode (smoother audio but more muffled)
Speech mode (Using triangle waves only) less data usage
Single channel mode.
More advanced pre iteration heuristics to reduce arpeggiation.
Bass distortion reduction. Experimental.
The single channel mode is useful for allowing two sid channels to operate while the "speech channel" is running.
There is an issue with increasing the sustain (I have used the gateoff/sustain change/gateon method for any sustain that is higher than the previous.
some test examples here. (Both examples pack to around 100 bytes per second!)

very nice, would like to see what it can do at like 1000 bytes / sec. |
