Audio Device In CHOP encoding and getting samples as binary

Hello all! I’m trying to perform some speech-to-text transcription using google cloud speech. To do so I’m using the Audio Device In CHOP. In order to do so I need to know how the audio is encoded and haven’t been able to find out what it is (LINEAR16, FLAC, etc.).

Additionally I need to convert the audio sample data into binary. To do so do I need just the most recent channel value or the vals(), and what does the channel actually store? Is it the wave data, the amplitude, etc.?

Thank you for any help!

All data in CHOPs are 32-bit floats, it doesn’t matter what the source is, it’ll be converted to 32-bit floats as it travels through the CHOP data flow. Audio will be values between -1 and 1.
