Recording Audio on the Raspberry Pi with Python and a USB ...
https://makersportal.com/blog/2018/8/23/recording-audio-on-the-raspberry-pi-with-python-and-a-usb-microphone
The Raspberry Pi is capable of recording audio through its USB 2.0 ports using the advanced Linux sound architecture (ALSA). The RPi can sample at 48kHz at a bit depth of 16-bits, which allows the user to record and playback fairly good quality audio.

Also: How to use an external USB audio interface with your Raspberry PI. Table of contents below! In this video, I'm solving the problems with my audio interfaces I encountered in my last video, install some audio software and build a sample-synthesizer (think Korg M1, or any workstation synth) from scratch, creating a string orchestra sound on ...
Audio sampling using SPI interface - Raspberry Pi Stack ...
https://raspberrypi.stackexchange.com/questions/44347/audio-sampling-using-spi-interface
Audio sampling using SPI interface. Bookmark this question. Show activity on this post. I want to record sound using an electret microphone and ADC (MCP3002), with Raspberry Pi 2 model B. Can I sample audio using the SPI interface on the Pi? I am using one microphone, and I need to get at least 20k samples per second.
Sampling Audio with Raspberry Pi and MCP3008 : raspberry_pi
https://www.reddit.com/r/raspberry_pi/comments/4ciqdi/sampling_audio_with_raspberry_pi_and_mcp3008/
Sampling Audio with Raspberry Pi and MCP3008. As a class exercise, my classmates and I are attempting to sample some very basic audio using the Raspberry Pi and an MCP3008 ADC. The spec for the exercise is that we need to be able to sample from 10 Hz to 10 kHz, and then output it using PWM. We've been trying to accomplish it in Python, but it seems to be sampling far too …
Sample rate to Bit rate | Raspberry Pi Audio
https://rpiaudio.wordpress.com/2012/02/22/sample-rate-to-bit-rate/
Sample Rate x Sample Resolution x Channels. For CD audio that’s: 44100 x 16 x 2 = 1411200 bits per second or 1.4 Megabits per second. Seeing this figure makes those of us familiar with compressed audio realise the sort of data rate savings it brings. “High quality” compressed audio tends to have a bit rate of between 300-400 kilobits per second.

ADC Sampling and FFT on Raspberry Pi Pico - Hackster.io
https://www.hackster.io/AlexWulff/adc-sampling-and-fft-on-raspberry-pi-pico-f883dd
Currently, one sample takes 96 cycles to collect. This yields a maximum sample rate of 48, 000, 000 cycles per second / 96 cycles per sample = 500, 000 samples per second. In order to sample slower, you can increase clock divisions. Setting CLOCK_DIV to 960 is a 10x increase in the number of cycles per sample, which yields 50, 000 samples per second.
