Frequently Asked Questions

What are the file size limits?
Free users can process files up to 20MB. Premium users can process files up to 50MB. Upgrade to Premium for higher limits and faster processing.
Does changing speed affect audio quality?
Our algorithm maintains high audio quality even at extreme speed changes. Quality loss is minimal with our advanced processing.
What is pitch preservation?
Pitch preservation keeps the original tone of voices and instruments when changing speed. Without it, speeding up makes audio higher-pitched and slowing down makes it deeper.
What audio formats are supported?
We support MP3, WAV, OGG, FLAC, M4A, AAC, and most common audio formats. The processed file will be downloaded as MP3 for compatibility.
Can I use this for video audio?
Yes, you can extract audio from video files and then modify the speed. However, you'll need to recombine the audio with video using video editing software.
