You can use convenient methods to retrieve that data or audioplayer objects created from that data. Methods for blocking and non-blocking recording, pausing and resuming recording and much more is available.

`recorder =` audiorecorder `()` ¶
`recorder =` audiorecorder `(fs, nbits, nchannels)` ¶
`recorder =` audiorecorder `(fs, nbits, nchannels, id)` ¶

  Create an audiorecorder object recording 8-bit mono audio at 8000 Hz sample rate.

  The optional arguments fs, nbits, nchannels, and id specify the sample rate, number of bits per sample, number of channels, and recording device ID, respectively. Device IDs may be found using the `audiodevinfo` function.
