Major changes
- 🎉🎉🎉 ASIO401 now supports the QA403 and QA402 audio analyzers! 🎉🎉🎉 (see usage docs)
- New configuration option:
fullScaleInputLevelDBV
- This is used to configure the QA40x input gain.
- This replaces the
attenuator
option, which is now deprecated as it is not flexible enough for the QA403/QA402 which has more than two input gain levels.
- New configuration option:
fullScaleOutputLevelDBV
- This is used to configure the QA403/QA402 output gain.
- Fix a bug that could prevent applications from working with ASIO401 if they issued a
GetLatencies()
call before aCreateBuffers()
call. See dechamps/FlexASIO#122. - The core streaming logic of ASIO401 underwent a complete rewrite.
- The new logic uses a double buffering mechanism on the backend side to make ASIO401 much more resilient to glitches/dropouts from missed thread scheduling deadlines, especially at higher sample rates.
- The priming logic was also improved to be more efficient, less prone to glitches, and more compliant with the ASIO spec.
Minor changes
- ASIO401 will now reject buffer sizes that are not multiples of 32 (for the QA401) or 64 (for the QA403/QA402) if output channels are used.
- Indeed it has been observed that the hardware will output garbled audio with such buffer sizes.
- ASIO401 will now abort pending I/O on stop.
- This should make the driver more responsive to stop commands, especially when large buffer sizes are used.
- Fix a bug where, if an host application calls
OutputReady()
after returning frombufferSwitch()
, ASIO401 may output corrupted audio. See dechamps/FlexASIO#180. - Incorrect calls made by the host application on an uninitialized driver will now return an error instead of crashing. See #20.
- ASIO401 will now refrain from logging if the logfile size exceeds 1 GB. See dechamps/FlexASIO#146.
- This is to avoid accidental disk space exhaustion when forgetting to remove the logfile.
- Fix a bug in ASIO401Test where it would always operate in "inhibit
OutputReady()
" mode even if the--inhibit-output-ready
command line option wasn't passed. - ASIO401Test default text output is now less verbose and more readable.
