The beginning of the video sound is not correct when playing , the audio of either the converted or the mp4 are correct

Hi Denis,

Do you mean missing beginning - high peak in waveform?

Send me please your MP4 video file + .pte project file.

I couldn't reproduce this problem with several my MP3 files. Audacity shows same waveform for extracted WAV file.

Hi

It's a more general problem
With Audacity I create a sinewave 440 Hz La.wav

I put two times this sound in a PTE project.

At the beginning of the sound, it's not "normal"

I export soundtrack in wav, and import it in audacity :

The beginning of the first sound

The beginning of the second sound

PTE transform a wav in wav and the value are very different. Moreover, the values of the same file are different if I put it at the beginning of the soundtrack or not

Please try a new version 9.0.18 BETA:

https://files.wnsoft.com/test/picturestoexe-setup.exe

This update improves audio playback and quality of waveform:

  • Fixed problem with playback of audio clips which appeared within first 50 ms of audio as a sound “click” and waveform was distorted. Usually this problem doesn’t appear, because first 200-300 ms of audio files contain silence. 
  • Fixed problem of cutting of last 20-50 ms in last audio clip. This problem also usually is not visible, because end of audio clips contain silence.
  • Slightly improved accuracy of audio keypoints (sound volume) during playback.
