Igor Posted March 26, 2018 Report Share Posted March 26, 2018 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. Link to comment Share on other sites More sharing options...
denisb Posted March 26, 2018 Author Report Share Posted March 26, 2018 The high peak we can see (video avi and video mp4) is not present in the video : the real sound is what you see "sound of video avi or mp4 Link to comment Share on other sites More sharing options...
Igor Posted March 27, 2018 Report Share Posted March 27, 2018 Denis, Please send me this MP4 video file. Now I'm working with new video/audio decoders for PTE 10 and I will check for this code. Link to comment Share on other sites More sharing options...

denisb Posted May 18, 2018 Author Report Share Posted May 18, 2018 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 Denis Projet1_May16-2018_17-22-22.zip Link to comment Share on other sites More sharing options...
Igor Posted May 18, 2018 Report Share Posted May 18, 2018 Denis, Thanks, I confirm this problem with audio. This issue appeared since v6.5. I'll try to find why it happens. Link to comment Share on other sites More sharing options...
Igor Posted May 30, 2018 Report Share Posted May 30, 2018 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.
