Is it necessary to use DAQ toolbox to realize simultaneous audio playing and recording via sound card? Can audioplayer and audiorecorder objects achieve that?

It is necessary to use either DAQ or DSP to get simultaneous audio playing and recording if you want the two to be synchronized.

If you do not care about the two being synchronized, the audioplayer() play() method is asynchronous, and the audiorecorder() record() method is also asynchronous, so you can start one and then the other while still being able to react to user events.

I would like to use Matlab and soundcard as a tester for audio gears. Matlab generates signal and capture response simultaneously for real-time analysis.

Then you probably want DSP Toolbox and configure for ASIO drivers.

If you were not using a sound card, then I would suggest DAQ, with timestamps on, so that you can do more precise analysis of latency and frequency response and phase effects.
