How To Stretch And Enhance Sounds Without Losing Quality

Ever wanted to stretch your favorite soundtracks beyond imagination? From studios to garage bands, sound stretching has profound applications due to spectral smoothness, special effects and features like binaural beats. Now, you can stretch a 4 minute audio to a unique 4 hours high quality listening experience using Paul’s Extreme Sound Stretch. Supporting popular audio formats including WAV, OGG, MP3, it enables ease of operation with advanced post processing effects to give ambient epics. The stretching amount is unlimited and the complexity can be increased according to the requirements. Unlike other audio manipulation tools, it loads onto your system smoothly and has negligible effect on the overall system performance. After adding the required audio file, you have the liberty to select the stretch parameter as well as the audio output size.

The utility does not process your file as a single file rather it treats it as numerous small chunks called Window. So, the window size has direct influence on the frequency spectrum and the sound quality. A smaller window size will have good time resolution but poor frequency resolution and vice versa. The onset sensitivity ranges from ‘ignore all onset’ to disabling stretching as the slider moves from left to right extremes.
