Volume control in QtMultimedia?

  • I developed a program for symbian that it should record and play raw audio data.
    The data are stored in a QBuffer and I use QAudioInput to record and QAudioOutput to play.

    But the volume of the output sound is very low.

    What can I do to increase the output volume?

  • You can proceed your raw data, which your store in your buffer, an increase volume to peak level(by multiply every point on some constant value), but be careful you can make "clicks" on your sound.
