Multichannel Audio Input and Output

Set up a continuous audio acquisition using a microphone.

Generate audio signals using a 5.1 channel sound system.

Set up continuous audio generation using multiple audio channels. The signal, a sample of Handel's "Hallelujah Chorus", is broken up into contiguous segments and played back in two parts. The first part of the example plays each segment on a single speaker and a sub-woofer. The second part plays each segment on a different set of speakers (a choir of voices).

Create an echometer sonar using audio data acquisition and signal processing, which can measure distance by determining the time of flight of a sound pulse reflected off of a surface.

Create an analog-triggered data acquisition app by using Data Acquisition Toolbox™ and App Designer.

Create an analog-triggered data acquisition app by using Stateflow®, Data Acquisition Toolbox™, and App Designer.

Create an app which acquires data from a DAQ device or sound card, displays a live data view, and logs data to a MAT-file.

Measure an impulse response using a National Instruments (NI) USB-4431 sound and vibration device. You set up the device, create an excitation signal to play, and simultaneously record the response. Finally, you compute the response from the recording and plot the results.
