Releases of WASAPI shared output

0.7 released on: 2025-11-14

  • Changed from internal manually handled resampling to use foobar's DSP chain with automatically injected resampler. The new core playback changes don't like output having high latency.
  • Added ability to use OS resampling by setting the resampling quality in advanced preferences to 0.

Note: Core resampling is used always on foobar2000 v2.25 since it had removed support for the required injected_dsps() output API function feature. The feature is restored on foobar2000 v2.26 preview newer than 2025-11-07.

0.6.25 current version, released on: 2025-11-06

  • Updated to new output API version to work around playback stalling with resamplers that have extremely high latency.

0.6.24 released on: 2024-03-30

  • Fixed latency reporting. The new API wants latency in samples so it needed converting from playback rate to source rate to match expected duration.

0.6.23 released on: 2024-03-23

  • Changed the component to request proper amounts of data to refill internal buffer with extreme ratios between incoming sample rate and Windows mixer.

0.6.22 released on: 2024-03-20

  • Changed to use latest output implementation.

0.6.21 released on: 2023-09-15

  • Reduced delay before playback actually stops when hitting stop.
  • Updated to the latest SDK.

0.6.20 released on: 2023-09-11

  • Changed some error messages to be more clear.
  • Increased timeout before stopping playback forcefully terminates the playback thread in case it's not responding.

0.6.19 released on: 2023-03-16

  • Recompile with the latest SDK in foobar2000 v1.5 compatible mode.

0.6.18 released on: 2023-02-06

  • Fixed a bug that playback didn't automatically stop after the last track under certain conditions.
  • Support for foobar2000 64-bit version.

0.6.16 released on: 2020-12-27

  • Added advanced config setting to adjust the quality scale of the automatic resampler.

0.6.15 released on: 2020-10-10

  • Fixed mix format reading to not require WAVEFORMATEXTENSIBLE structure.

0.6.14 released on: 2020-08-04

  • Added 22.2 channel downmixer.

0.6.13 released on: 2020-07-25

  • Fixed playback of very short tracks.

0.6.12 released on: 2020-06-29

  • Added ability to play over 8 channel audio content with missing channel mapping.

0.6.11 released on: 2020-06-27

  • Ignore device disappearing error when playback is paused.

0.6.10 released on: 2020-06-24

  • Improved standby handling. Playback should no longer error out when the machine is resumed from sleep.

0.6.9 released on: 2020-06-16

  • Added standby event handling.

0.6.8 released on: 2019-09-28

  • Removed locks from the playback thread.
  • Added error details previously only shown on console to the error popup.

0.6.7 released on: 2019-09-03

  • Fixed stuttering with extreme downsampling ratios.
  • Problem was introduced by the processing change in v0.6.5.

0.6.6 released on: 2019-06-28

  • Reduced the glitch size when default audio device changes and buffer gets converted to the new format.
  • Fixed player getting stuck when pausing a short track (bug introduced in 0.6.5).

0.6.5 released on: 2019-06-27

  • Fixed player UI freeze while processing very large audio chunks.

0.6.4 released on: 2019-06-22

  • Fixed noise issue during channel count change when automatic resampling was active.

0.6.3a released on: 2019-06-17

  • Version 0.6.2 introduced glitches when buffer refill events were signalled too early.
  • Restored the retry logic for most parts to match v0.6.1.

0.6.3 released on: 2019-06-17

  • Fixed fade-in missing when initial playback didn't start from the beginning of a track.

0.6.2 released on: 2019-06-15

  • Fixed audio glitches when switching tracks.
  • Changed playback thread not to abort so easily on buffering problems.
  • Increased the fade duration to 50 ms to improve interpolation smoothness.

0.6.1 released on: 2019-04-07

  • Reverted the 0.6 buffering change.
  • Default device change mid-playback will now resample and convert the already buffered samples to new target format.
  • The transition isn't as smooth as with 0.6 but better than in prior versions.
  • Fixed a glitch when seeking while paused.

0.6 released on: 2019-03-31

  • Buffer is no longer flushed when using the default device and the device changes mid-playback.
  • Added a short fade-in after default device change.

0.5.8 released on: 2019-03-21

  • Improved compatibility with audio drivers that signal events incorrectly.

0.5.7 released on: 2019-03-14

  • Mixer setting report now includes channel mask configuration.

0.5.6 released on: 2019-03-09

  • The output device was incorrectly reinitialized when default changed even when not using default output.

0.5.5 released on: 2019-03-09

  • Made default output notice changes and automatically switch to new device.

0.5.4 released on: 2019-02-15

  • Hopefully fixed playback thread init failure related crashing.

0.5.3 released on: 2019-01-31

  • Added COM library initialization to device enumerator.

0.5.2 released on: 2018-10-29

  • Fixed crash on device close.

0.5.1 released on: 2018-10-27

  • Volume adjustment was incorrectly delayed during initial playback start.

0.5 released on: 2018-10-18

  • Fixed glitching with sub 100 ms output buffers, the component incorrectly played silence when its buffer went empty.
  • Eliminated need for Sleep() which should make the component immune to timer resolution fluctuations.

0.4.1 released on: 2018-10-15

  • Fixed device identification by GUID.
