This article mainly introduces the relevant knowledge of "how to use Matlab to make a simple version of the octave sauce game". The editor shows you the operation process through an actual case, the operation method is simple and fast, and is practical. I hope this article "how to use Matlab to make a simple version of the octet sauce game" can help you solve the problem.

Effect.

Game mode

Yell after plugging in the headphones on the computer!

Description

1) to use this code, you should first install:

Audio Toolbox toolbox, the version used by bloggers is:

Audio Toolbox version 3.0 (R2021a)

2) in order to ensure that the game starts after loading all the materials, the loading interface is set to stop for 3 seconds and then start running the game.

If you hang up as soon as you enter the interface, the resource should be loaded for too long. Please close the window and try to run it again.

Code for the main part of the toolbox

1) basic settings

Here, I don't bother to change the truncated data recognized by voice commands that are copied directly. You can change it according to your needs:

[audio_t,fs] = audioread ('stop_command.flac'); classificationRate = 20 leading adrenders audioDeviceReader (' SampleRate',fs,'SamplesPerFrame',floor (fs/classificationRate)); audioBuffer=dsp.AsyncBuffer (fs)

Sound signal drawing:

If ishandle (fig) audio_t=adr (); write (audioBuffer,audio_t); audio_y=read (audioBuffer,fs,fs-adr.SamplesPerFrame); audio_x= (0: (length (audio_y)-1)). / (length (audio_y)-1); audioHdl.XData=audio_x; audioHdl.YData=audio_y;end

Note:

After the code, the sound acquisition device must be released and the timer real class must be deleted, otherwise there will be the following prompt bug:A given audio device may only be opened once.

That is, a device is turned on twice.

Therefore, you need to set the following callback to avoid this situation:
