The sample rate is also called as sample frequency, higher the sample frequency obtains a signal which is similar to original analog signal for good audio quality. The file size depends upon the sample frequency. The bit depth refers to no. of bits in each sample, determines the maximum signal to noise ratio. The bit depth may be 16-bit, 24-bit, 32-bit, for …

Get the preferred sample rate. AudioSessionGetProperty (kAudioSessionProperty_CurrentHardwareSampleRate) Then you can set up your audio processing chain with the correct sample rate. As for playing back audio, you can use any sample rate and the API should convert it to the hardware's output sample rate.

The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second. This is the standard for most consumer audio, used for formats like CDs. This is not an arbitrary number. Humans can hear frequencies between 20 Hz and 20 kHz.

The most common values for the sampling rate is the aforementioned 8kHz (most common for telephone communications), 44.1kHz (most common for music CDs), and 48kHz (most common for audio tracks in movies). Lower sampling rates mean less samples per second, which in turn mean less audio data, since there is a smaller number of sample points to represent the audio.
