# PipeWire 0.3.54 (2022-07-07)

This is a quick bugfix release that is API and ABI compatible with previous 0.3.x releases.

## Highlights

  • Some critical bugs in the new audioconvert were fixed. The old adapter had internal buffering that was abused in some places.
  • The bluetooth sources were rewritten using a ringbuffer to make them more reliable to jitter and remove old audioconvert behaviour.
  • Many improvements to the audio converter.
  • Native DSD128 and up is now supported by pw-dsdplay.

## tools

  • Support DSD128 to DSD512 as well by scaling the amount of samples to read per time slice.

## SPA

  • Format conversion is now generated with macros to remove duplication of code.
  • 24bits conversions were rewritten to use the generic conversion functions.
  • Temporary buffers in audioconvert are now made large enough in all cases.
  • Fix draining in audioconvert. This fixes speaker-test.
  • Fix the channel remapping.
  • Audio conversion constants were tweaked to handle the maximum ranges and provide lossless conversion between 24bits and floats.
  • Vector code and C code are aligned and the unit tests are activated again. A new lossless conversion test was added.
  • Fix an underrun case where the adapter would not ask for more data.
  • Fix PROP_INFO for audioconvert.
  • Use the blackman window again for the resampler, the cosh window has some bugs that can cause distortion in some cases.
  • Add more unit tests for audioconvert. Add end-to-end conversion tests.
  • Don't leak memory in format converter.

## pulse-server

  • Card properties are now also added to sinks and sources, just like in pulseaudio.
  • Increase the maxlength size to at least 4 times the fragsize to avoid xruns.
  • Fix a race when setting default devices.

## Bluetooth

  • The source was rewritten to use a ringbuffer. This avoids regressions caused by audioconvert.
