CLAM Buffer Ports TODOs
Use audio-buffers whenever possible
- Convert processings
- Use audio-buffer ports
- Use audio-buffer policy
- Remove duplicated processings
- Adapt networks that combine audio-buffer and audio-stream ports (using Buffer2Stream, etc)
- Test them in dynamic buffer-size hosts (like ardour/ladspa)
- Port LadspaWrapper to audio buffer ports (instead of audio stream ports)
- Duplicate [done]
- Test in dynamic buffer-size host
- Eliminate stream-port version
Optimize Backends copies
- AudioSources and Sinks should map the memory of the host
- Check that all the hosts (Jack, Ladspa, Portaudio) use 4 bytes floats
- Force clam audio samples format to floats
- reallocate a pool of audio buffers at Config time to avoid allocating memory at runtime, which is non realtime safe.
Audio-buffer Processing policy
- Do not call port.SetSize(1) and portSetHop(1), since it is the default behavior.
- Do not allocate audio buffers in ConcreteConfigure (since the connections could not exist)
- Do an implicit allocation of output audios in the Do (that means that will allocate only once): outbuffer.SetSize( inbuffer.GetSize() ) where outbuffer and inbuffer are the port.GetData()
- This will change by using a pre-allocated audio-buffer pool
- Using callgrind to compare the efficiency with the buffer implementation.
- Test the BackendBufferSize to demostrate the correct function.
- Create AudioSink with Buffer.
- Create AudioSource with Buffer.
- Stream2Buffer and Buffer2Stream using the BackendBufferSize.
- (David) NetworkEditor: Allow connecting multiple channel into the single conection in AudioSink.
- Ex. 15 channels (like Hoa) to single conection (AudioSink)
- Allow the hosts/backends to change its buffers size at runtime.
- optimization: do not reallocate audio buffers in Do() when resizing to smaller size.
