Generating a sequence of tones

I need to generate 60dB Blackman windowed sinusoidal waves of 500Hz frequency with 18ms duration and 200ms silent duration. I also need to know the masking of signal and how to generate it as blocks of signals.

Okay. What is your question? What have you tried so far and which problem occurs?

Hi Jan,

How to create a 3 and 4 channel wav file to play into three and 4 different channels using the matlab. I have generated a 2 channel wav file but how to increase the channel number to play it out as to different channels without any delays. I am also in search of a method to play it to 4 diff channels through a soundcard. Can u pls give me support?

The MATLAB dound function will only allow you to play two channels. See the documentation section on y (link) for a discussion.

but what about the multichannel audio output and so in the matlab

[Star Strider]

In core MATLAB, you are limited to two channels.

The Audio Toolbox (that I don not have, so also no experience with it) apparently allows three. See: Device output channels (link) and audioDeviceWriter (link) for details.

Is the Blackman window in the time domain, or frequency domain?

In both domains
