Full Changelog: v0.5.1...v0.5.2

Release 0.5.1

• Now support Python3.10
• Bugfix #67: When the channels argument of Aserver and Arecorder has not been set it was determined by the default device instead of the actual device.

Release 0.5.0

• Make Aserver a context that can wrap play inside. This context will handle boot() and quit() automatically.
• Move OSX/Linux CI to Github Action from TravisCI.
• Bump numpy dependency, numpy.linspace usage is updated.
• Make Asig.play() arguments explicit.
• Asig.dur property that returns the duration in seconds of the signal

Release 0.4.2

• Add logging helper function.
• Make sure pya runs on Python3.8
• Bugfix #43: Handle None as a return value of get_server_info in pya.helper.backend.determine_backend (thanks @paulvickers)

Release 0.4.1

• Fix bug of extend mode result in a change of dtype (from the default f32 to f64). Now it is fixed at f32.
• Add convolve() method. A convolution method (default to fft). Now you can apply reverb, do autocorrelation to the signal. (#40)
• Update Ugen docstring and remove deprecated variable names (#39)
• namespace improvement.
• sanic and notebook are now optional: If you plan to use JupyterBackend, install pya with pip install pya[remote] (#38, #41)

Release 0.4.0

• new Amfcc class for MFCC feature extraction
• new helper.visualization.py and gridplot()
• optimise plot() methods of all classes for better consistency in both style and the API
• new helper functions: padding, is_pow2, next_pow2, round_half_up, rolling_window, signal_to_frame,
  magspec, powspec, hz2mel, mel2hz_
• Fixed bug that for multichanels spectrum the rfft is not performed on the x-axis

Release 0.3.3

• Bugfix #34: Improve indexing of Asig
• Added developer tools for documentation generation
