QAudioOutput infinite loop

[Jojo]

Hello @ all,

I'm sorry for the bad english
Here's my problem:

I have a class which plays a sound wave with a QBuffer as QIODevice, a QBytearray as wave buffer and a QAudioOutput, but only for limited time.
For my program the soundwave must play 'forever' until I stop it.
But while playing, I must be able to edit the wave.

Do you have a solution for this problem?

Thanks for all answers!

Jo

Hi and welcome to devnet,

Why not have e.g a QTimer calling a function generating the audio data ? It could also be done in a secondary thread.

Hope it helps

Thanks for your answer.
I'll try it and give you a reply

Hi,
My solution, reimplement QBuffer::read():
https://github.com/alphaonex86/CatchChallenger/blob/master/client/base/QInfiniteBuffer.cpp
https://github.com/alphaonex86/CatchChallenger/blob/master/client/base/QInfiniteBuffer.h
Work well to do an audio loop.
Cheers,
