[Release] Pyo 1.0.0 (Python dsp library)
by Olivier Bélanger 07 Aug '19

07 Aug '19

Hello all, After almost a year of hard work, I'm very glad to announce the release of pyo 1.0.0, available for python 2.7, 3.5, 3.6 and 3.7. Pyo is a Python module written in C to help real-time digital signal processing script creation. It provides a complete set of classes to build audio softwares, compose algorithmic musics or simply explore audio processing.It is available for Windows, macOS and linux. It is released under the LGPL 3 license. Official web site: http://ajaxsoundstudio.com/software/pyo/ pyo's documentation: http://ajaxsoundstudio.com/pyodoc/ Latest sources and bug tracker: https://github.com/belangeo/pyo The main change in this release is the installation process. The package is now uploaded to pypi.org and can be installed (for 32-bit or 64-bit) under MacOS, Windows and linux with pip. Just run the command: python -m pip install pyo For all the details and how to uninstall version prior to 1.0.0, see this page in the documentation: http://ajaxsoundstudio.com/pyodoc/download.html Bug Fixes: - Fixed phase of sawtooth and ramp waveforms in the LFO object. - Embedded: Fixed crash on first load when embedding pyo in a juce plugin. - Embedded: Remove the wx import before importing pyo to prevent a crash on MacOS. - Embedded: Added a BPM variable in the embedded interpreter and a function in PyoClass to change it according to the BPM of a DAW, for instance. - Embedded: Better handling of bad code when reading file in embedded pyo. - Fixed bug in OscDataSend.addAddress(). - Fixed BPF tables (LinTable, ExpTable, ...) memory allocation corruption. - Fixed SIGSEGV when multiplying a plain number and a base object. - Jack audio backend does not ignore duplex value anymore. New features: - Added PYO_SERVER_MIDI and PYO_SERVER_WINHOST environment variables to set default values for the audio server (user can also define PYO_SERVER_AUDIO). - Added one-sample delay function and sr constant to the Expr api. - Added complex numbers (and complex one-pole/one-zero filters) to the Expr API. - Added a new object: PyoGuiKeyboard, a virtual MIDI keyboard. - Added keyboard() method to the Notein object (opens a virtual midi keyboard). - Added computer keyboard bindings when the Notein's keyboard widget has the focus. - Added a getPyoExamples() function and changed example function to be able to execute one of the example. - Added a new object: SVF2, a 2-pole state variable filter with many filter types. - Added two arithmetic objects: Div and Sub. - CallAfter's time and arg arguments can be changed dynamically. - Fader and Adsr now send a trigger at the end of the envelope. - Added a clear() method to Linseg and Expseg objects. EPyo: - Fixed crash when trying to read a faulty preferences file. - Added auto complete for cpp file (from corresponding header file). - Added a 'Reload Current File' menu command. - Added zoomin/zoomout function in the documentation window (Ctrl-- and Ctrl-+). - Added multiple views (splitted windows) functionnality. - Fix search ctrl behaviour in the documentation window. Auto Start Children (new feature): These changes offer the possibility to control start/stop of all objects in a processing chain at once. See the documentation of the following methods for more details. - Server.setAutoStartChildren(). - PyoObjectBase.preventAutoStart(). - PyoObjectBase.useWaitTimeOnStop(). - PyoObjectBase.addLinkedObject(). - PyoObjectBase.setStopDelay(). - PyoObject.stop(). - PyoPVObject.stop(). New example categories: - Dynamic range of audio signals - Calling python functions from audio objects - Using tables - How to use MIDI with pyo - Multirate audio processing Olivier Belanger belangeo(a)gmail.com http://olivier.ajaxsoundstudio.com/ ---- <P><A HREF="http://ajaxsoundstudio.com/software/pyo/">Pyo 1.0.0</A> - short Python DSP library.
