Hi I’m looking at putting together a device for recording memos and saving them to an sd card or other type of internal storage using a headset microphone with a TRS plug. I’m pretty sure I’d need something a bit better than my arduino uno for processing audio and was suggested by a friend to look at the dfrobot mini mp3 but that looks to be just for playing audio files.
Would anyone be able to suggest a sound card with a trs port or that I can wire one to that i could record audio to and access it via an sd card or micro sd card? And would I need to use this with an arduino or could I run it without. (Being able to play audio from would be a bonus)
