I've been wondering for a while now about the recording capabilities of my iPhone. With the addition of the Apogee Mic and others it could be a good little recorder maybe?

But I wonder, does any one know the maximum sample rate / bit depth of the iPhone?

I personally have the iPhone 4 with iOS 5.

Thanks! James

I'm 99.9% sure it's 48kHz, 16-bit Mono (or Stereo if you have a plug-in mic of some sort which supports Stereo). I use the FiRe app which is one of the most comprehensive and professional-geared recording apps, and that's the max it supports. On older iPhones like the 3G I believe it was only 44.1kHz.

Thank you for your answer. And just so everyone who searches for this question, after you said about the FiRe app, I contacted the Audiofile Engineering guys and asked about this, their response was: "FiRe 2 records @ 48 kHz/16-bit. In a future update, we'll allow users to change the sample rate of their recordings so they're not limited to just 48 kHz." ...I do hope that Apple will allow future iPhones/iPod Touches to support 24bit as along with a decent iDevice compatible microphone (the Apogee Mic?) it could be a very handy and portable quick and dirty sound recording device. – littlejim84 Aug 31 '12 at 8:11
