Answer 1

[Daniel Shub]

What about

sound(randn(4096, 1), 8192)

Answer 2

[Jan]

WarnWave = [sin(1:.6:400), sin(1:.7:400), sin(1:.4:400)];
Audio = audioplayer(WarnWave, 22050);
play(Audio);

[IceQueen]

Thank you. The beep sounded exactly like the error. I threw your solution in a function and gave it a short name. Thanks!

[abderrazak chahid]

It is very helpful, Thank you, Jan

[Min Son]

Cool sound!

[v k]

Need something similar to this, which gives a sound when the Whatsapp message comes, or an incoming SMS. A whooshing or a swishing sound.

What structure of WarnWave will give such a notification sound?

Answer 3

[Jan]

Data = load('handel.mat');
sound(Data.y, Data.Fs)

It seems wrong to me to use hallelujah as an alert sound to the "wrong" case. I think would be cool to probe the system settings for the alert sound and use that. You probably also want to unmute and maximize the volume.

[Jan]

I think, and it's near to Christmas, that Hallelujah is a nice counterbalance, when the workflow is impeded by a problem.

I recommend never to unmute automatically: When my son has fallen asleep, I mute the speakers of my laptop.

Well, I admit, that this was the situation of the last year. Currently: When my son mutes the speakers of my laptop, I fall asleep immediately.

[Daniel Shub]

I agree, but for alerts you never know.

[Benjamin Wong]

this is absolutely briliant

Answer 4

[Jan]

This calls the message sound of the operating system:

beep

[Daniel Shub]

I had forgotten about beep.

[Paul Hoffrichter]

beep beep beep

Nice and succinct. Thanks.

Answer 5

[Daniel Shub]

So here is an absolutely ugly Windows XP hack that gets the SystemExclamation sound from the registry and replaces environment variables with the correct values and then plays the sound.

[~, tempStr] = system('reg query HKEY_CURRENT_USER\AppEvents\Schemes\Apps\.Default\SystemExclamation\.Current');
[~, valueStart] = regexp(tempStr, 'REG_EXPAND_SZ  ');
soundStr = tempStr(valueStart+1:(end-1));
envVarSymbol = strfind(soundStr, '%');
while length(envVarSymbol) >= 2
  soundStr = [soundStr(1:(envVarSymbol(1)-1)), ...
    getenv(soundStr((envVarSymbol(1)+1):(envVarSymbol(2)-1))), ...
    soundStr((envVarSymbol(2)+1):end)];
  envVarSymbol = strfind(soundStr, '%');
end
[x, Fs] = wavread(soundStr);
sound(x, Fs)

I need to think about this idea more. Interfaces really should be playing system sounds (yuk, who actually has system sounds set to on) at the appropriate times.

[v k]

'wavread' incorrect.

[v k]

replaced by 'audioread'.
