Responsibility for calling fluid_sequencer_unregister_client() in case of FLUID_SEQ_UNREGISTERING events has been moved to fluid_sequencer_send_now(). In other words, a FLUID_SEQ_UNREGISTERING event now really unregisters the client, no matter how the client's callback function looks like.
Avoids leaking the sequencer clients if implementations do not unregister them explicitly.
Also fixes another memory leak if fluid_sequencer_register_fluidsynth() clients were unregistered with fluid_sequencer_unregister_client() rather than by sending an unregistering event.
This adds new LFO modulators:
- these modulators are computed on the fly, instead of using lfo lookup table. Advantages:
- Avoiding a lost of 608272 memory bytes when lfo speed is low (0.3Hz).
- Allows to diminish the lfo speed lower limit to 0.1Hz instead of 0.3Hz.
A speed of 0.1 is interesting for chorus. Using a lookup table for 0.1Hz
would require too much memory (1824816 bytes).
- Make use of first-order all-pass interpolator instead of bandlimited interpolation.
- Although lfo modulator is computed on the fly, cpu load is lower than using
lfo lookup table with bandlimited interpolator.
Also adds a stereo unit controlled by WIDTH macro. WIDTH [0..10] value define a stereo separation between left and right.
- When 0, the output is monophonic.
- When > 0 , the output is stereophonic.
WIDTH is currently fixed to maximum value to provide maximum stereo effect.
This document explains what sostenuto pedal is compared to sustain pedal. It is intended for a musician playing live. It gives information about specifications and implementation in fluidsynth.
This brings in support for compressed soundfonts (sf3) for Android.
We need libsndfile.so, but it has various dependencies (libogg, libvorbis,
libflac), which are somewhat annoying to build if you do everything
by yourself.
Fortunately cerbero has recipes for libogg, libvorbis and libflac.
I added custom recipe for libsndfile in the referenced cerbero fork, and
therefore the changes could be just in cerbero world.
This set of changes implements audio drivers for Android, OpenSLES and Oboe. The changes in the original sources are kept minimal so that it should be easily maintained.
