pyFLAC: Real-time lossless audio compression in Python #Audio #Python @Sonos
FLAC is the go-to compression algorithm for audio if you want to maintain a perfect reconstruction of the original data. FLAC stands for Free Lossless Audio Codec. Maintained by Xiph.org, it is free and open-source, and remains the most widely supported lossless audio codec. Other audio compression techniques such as MP3 or AAC can remove perceptually redundant information in the signal.
Sonos has created pyFLAC: a Python library for realtime lossless audio compression using libFLAC.
In the spirit of open-source, we are releasing pyFLAC as a free-to-use package which can be installed directly from PyPi using pip.
pip3 install pyflac
Below is a simple example of how you might use pyFLAC alongside python-sounddevice to capture raw audio data from a microphone, and then add the compressed audio to a queue for processing in a separate thread.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
