* Avoiding cutting all bsinc resampler output at scale 0Chris Robinson2021-02-242-9/+8
| | | | | | | | | | | | This is mostly for the SampleConverter, used by some capture backends. When recording at really low rates, like 5512hz, with a device capturing at a higher rate like 44100hz or 48000hz, it hits the filter's downscaling limit and produces pure silence. In such cases, it's better to just accept some aliasing noise so that the app will still get some recognizable audio. The alternative would be to scale the desired rate by 2x, 3x, etc until it's above the bsinc limit, then take every 2nd, 3rd, etc sample of the result as if by an extra simpler resampler pass.

* Avoid an unnecessary loop iterationChris Robinson2021-02-231-2/+3

* Adjust the bsinc filter table packingChris Robinson2021-02-234-41/+29
| | | | | | | | Now each scale's filter and phase delta are interleaved for each phase index, followed by the scale and scale+phase delta for each phase index. This ensures no holes in the filter coefficients for the fast bsinc resampler for a given run, while keeping the scale deltas in the same vicinity for the non-fast bsinc resampler.
* Remove unnecessary use of SSE2 intrinsicsChris Robinson2021-02-211-2/+1
| | | | | The compiler is producing the same results either way, since the upper bit results are never used.

* Add enumeration to the JACK backendChris Robinson2021-02-131-35/+84
| | | | | | | | Port names seem to be structured as <device_name:channel_name> or <app_name:channel_name>. I'm not sure if this is always the case, but it seems some other apps expect something like this. Also fix the port selection to exclude MIDI ports and allow non-physical ports.

* Rework fading of stopped soundsChris Robinson2021-01-271-22/+13
| | | | | | | Voices that stop and have no more accessible samples now fade out over 64 samples max. The extra loaded samples are also prevented from moving away from 0 amplitude. Paused voices that still have samples will still fade out over the whole mix.

* Use a deque for the source buffer queueChris Robinson2021-01-252-149/+121
| | | | | | This mainly avoids having to allocate ~64-byte structures individually. The mixing voice still holds the queue as a linked list so as to be container- agnostic.

* Remove some unnecessary function attributesChris Robinson2021-01-231-4/+4
| | | | | | | | The alloc_size was wrong anyway since the function parameter takes the number of objects to be allocated and the attribute declares which is the number of bytes. The assume_aligned is unnecessary since the function is inlined and al_malloc/al_calloc already have appropriate attributes for the compiler to see.
