If it is in stereo, the array has two columns-one for each channel.ĭisplays all property information about audio recorder y.Īudio recorder objects have the properties listed below. If the recording is in mono, the returned array has one column. For int8, values are between -128 to 127. For double and single, the array contains values between -1 and 1. If type is omitted, it defaults to 'double'. Supported data types are double, single, int16, int8, or uint8. type is a string containing the desired data type. Returns the recorded audio data to the MATLAB workspace. If 1, recording is in progress.Ĭreates an audioplayer, plays the recorded audio data, and returns a handle to the created audioplayer.Ĭreates an audioplayer and returns a handle to the created audioplayer. Restarts recording from where recording was paused. Same as record, but does not return control until recording completes. y represents the name of the returned audio recorder. Returns a handle to an audio recorder object using the audio device specified by its id for input.Īfter you create an audio recorder object, you can use the methods listed below on that object. For mono or stereo, channels must be 1 or 2, respectively. The value of n bits must be 8 or 16 (or 24, if a 24-bit device is installed). Fs can be any sampling rate supported by the audio hardware. Returns a handle to an audio recorder object using the sampling rate, Fs ( in Hz), the sample size of n bits, and the number of channels. Returns a handle to an 8-kHz, 8-bit, mono audio recorder object. On 32-bit, Windows-based machines with an installed 24-bit audio device, audiorecorder supports 24-bit recording. To use all of the audio recorder object features, your system must have a properly installed and configured sound card with 8- and 16-bit I/O and support for sampling rates of up to 48 kHz.
