1.0.0 Catch GStreamer’s exception when necessary components, such as Silently setting the duration field to None. 1.0.1 When GStreamer fails to report a duration, raise an exception instead of 1.0.2 Send SIGKILL, not SIGTERM, to ffmpeg processes to avoid occasional hangs. 1.0.3 Use the rawread (standard-library) backend for. 1.1.0 Add support for Sun/NeXT Au files via the standard-library sunau

1.2.0 Add support for FFmpeg on Windows (thanks to Jean-Christophe Saad-Dupuy). 1.2.1 Fix an unhandled exception when opening non-raw audio files (thanks toįix Python 3 compatibility for the raw-file backend. 1.2.2 When running FFmpeg on Windows, disable its crash dialog. Gobject-introspection API (and is compatible with Python 3). PyGObject (thanks to 2.1.5 Properly clean up the file handle when a backend fails to decode a file.įix parsing of “N.M” channel counts in the FFmpeg backend (thanks to a crash in the raw backend when a file uses an unsupported number ofīits per sample (namely, 24-bit samples in Python = 1.0.įix some Python 3 crashes with the new GStreamer backend (thanks 2.0.0 The GStreamer backend now uses GStreamer 1.x via the new Linux (thanks to suppressing SIGINT in the GStreamer backend on older versions of Try (thanks once again to Windows, avoid opening a console window to run FFmpeg (thanks to 2.1.6 Fix a “no such process” crash in the FFmpeg backend on Windows Subsystem for 2.1.7 Properly close some filehandles in the FFmpeg backend (thanks and maddec backend now always produces bytes objects, like the otherīackends (thanks to an audio data memory leak in the GStreamer backend (thanks again can now optionally specify which specific backends audio_open should Version History 2.1.9 Work correctly with GStreamer 1.18 and later (thanks to 2.1.8 Fix an unhandled OSError when FFmpeg is not installed.

You can use theĪvailable_backends function to get a list backends that are usable on theĪudioread is “universal” and supports both Python 2 (2.6+) and Python 3 (instead of trying them all, which is the default). Unsupported by the backends if the file doesn’t exist, a standard IOErrorĪ second optional parameter to audio_open specifies which backends to try This exception is only used when the file type is Package.) If no backends succeed in opening the file, a DecodeErrorĮxception is raised. (Each backend is implemented in a module inside the audioread The audio_open function transparently selects a backend that can read theįile. duration is the length of the audio in seconds (a float).samplerate is given in Hz (an integer).channels is the number of audio channels (an integer).(Currently, these PCM format parameters are not configurable, but thisĪdditional values are available as fields on the audio file object: Each buffer is a bytes-like object ( buffer, bytes, orīytearray) containing raw 16-bit little-endian signed integer PCMĭata. Print(f.channels, f.samplerate, f.duration)īuffers in the file can be accessed by iterating over the object returned fromĪudio_open. Use the library like so: with dio_open(filename) as f: The standard library wave, aifc, and sunau modules (for.FFmpeg or Libav via its command-line interface.I also found some other blog or issue about Dialogic ADPCM.Decode audio files using whichever backend is available. Because the original Dialogic ADPCM algorithm is decode 4bit to 12bit, not 16bit. The center of the signal deviates from the zero axis as a whole. But, the wav file's time domain waveform deviant. I can implement vox file to wav file by use sox. You also can use command "sox" to do convert.

I cound't find how to install it but I found a offline-way to use it.And it seems like many. vcecopy.exe was provided by the "Dialogic Co" and documents is here.

You can got other transfor tools in here. Vox2Pcm.exe was provided by the "BlueSpace Co" open source.

Follow his instructions, I changed his code to Dialogic ADPCM.Ģ. I got in touch with him, and he gave me some ideas. Thanks to the zhanzr !!!! I found his blog about IMA ADPCM, which similar to Dialogic ADPCM. copy 'use-exe-tool/vox_2_wav.py' and 'use-exe-tool/Vox2Pcm.exe' to your folderĪnd the lower part is the result of python code.īut the one down there can keep data in the RAM not use HDD, Time-consuming IO are avoided.ġ.

exe file to do the conversion from the command line.(better effect) Or use Python implementation of the Dialogic ADPCM algorithm.(more convenient) This is a way to convert audio vox file (Dialogic ADPCM) to wav file (PCM) via python.
