Recording audio at CD quality (44.1KHz 16 bit) is not practical with any Arduino I know of. They don't have fast enough processors or sufficient memory/fast storage. BTW the answer to a question like "How long do you want to record" should be a time, the minimum acceptable time. E.g. 5 seconds or 2 hours are useful answers.

Record Audio to your Audino Mega SD card. The audio file can be played back on a standard audio application or analysed byte by byte. This Instructable will show you how audio input can be repeatedly added to a 512 byte buffer and then transferred to a SD card in real time. The period recorded can be altered.

I was juggling the internet to find devices which record voice and play it again. I found out ISD1820, which is so reasonable (only 3$), and can record sound alone using some rec. and play button. I require to control this device using Arduino, I mean recording and playing voice through Arduino only.

MAX9814 (shown in the image above) records the sound and transmits it to the Arduino. Then, the Arduino converts the sound into .wav format and stores it inside a MicroSD card module that is also connected with the Arduino. There are many pins available in the MAX9814 module, but, majorly the VCC, GND, and out pins are used.

Arduino UNO For audio recording, we need to have a sampling rate of 44.1 kHz. While the Arduino ADC can theoretically sample at a maximum of about 77 KhZ, I am recording at about 16 kHz and still getting a decent recording, that's …

You can record with ADC, 10-bit sound quality will be low (like a telephone), and you need to save to SD Card, there is not enough SRAM on arduino to store sound there. I don't know about digitizing with Arduino and sending to Pi for storage as it is digitized, I suppose that could be made to work if the Pi could save it fast enough.
