Arduino Audio Project Help...

Hey guys,

I have an application where I need to record audio via a microphone, onto a device with an SD or MicroSD card. I then need to be able to connect to this device and retrieve the audio files. Simple right?..

So, question is… can I do this using Arduino kit?

Will this be very modular and self-designed OR is there already an Arduino product out there that Im not aware of that does exactly this? The closest thing I could find was some kind of Arduino Audio Shield. But it had a whole load exttra functinality that we simply wouldnt use.

As always… looking forward to, and am grateful for, any advice.

Cheers

Matt

How much are you interested in spending?

You’re going to need a shield of some sort if you want to put the data on an SD card. An Arduino all by itself lacks the speed needed to record audio data with any fidelity so I wouldn’t be so quick to dismiss a shield that seemingly had more functionality than you need. Which leads me to ask :

  1. How many audio channels are you planning to record ?

  2. What sample rate is desired ?

  3. What bit depth ?

  4. Are you looking to compress the data or store it as raw samples ?

  5. How long of a continuous time period will you need to record ?

  6. Why an Arduino vs some other available commercial product ?

ps - What shield did you see above ?
