Frequently Asked Questions

What is slowed & reverb and why is it popular?

Slowed & reverb is an audio effect technique that reduces playback speed and adds spatial reverb to create a dreamy, atmospheric sound. It became viral on platforms like TikTok and YouTube because it transforms familiar songs into emotionally evocative experiences, perfect for aesthetic videos and relaxation content. The effect creates a sense of nostalgia and depth that enhances the emotional impact of the music.

Why is file compression important for slowed & reverb tracks?

File compression is crucial for slowed & reverb audio because the effect naturally extends the duration of tracks, which can dramatically increase file size. Our tool implements advanced compression algorithms that keep output files small (around 5MB for a 3MB input) while preserving audio quality, making your creations perfect for sharing on social media, messaging apps, and websites without quality loss.

What settings work best for different music genres?

For pop and R&B tracks, we recommend 75-80% speed with medium reverb (50-60%). Hip-hop and rap usually benefit from 70-75% speed with heavier reverb (60-70%). Electronic music works well at 80-85% with moderate reverb and longer decay. For acoustic and instrumental tracks, try 75% speed with subtle reverb (40-50%) to preserve clarity. Our tool offers genre-specific recommendations to help you achieve the best results.

Is this tool completely free to use?

Yes, our Slowed & Reverb Creator is completely free to use with no hidden fees, account requirements, watermarks, or time limitations. We believe in providing high-quality audio tools that are accessible to everyone.

How is my privacy protected when using this tool?

Your privacy is our top priority. All audio processing happens directly in your browser using Web Audio API technology. Your audio files are never uploaded to any server, stored, or shared. Everything processes locally on your device, ensuring complete security and privacy.

What are the optimal settings for viral TikTok slowed & reverb effects?

For TikTok-ready slowed & reverb effects that tend to go viral, we recommend using 75% speed, 65% reverb, 3-4 seconds decay, and a slight bass boost (+3dB). These settings create the perfect balance of dreaminess and clarity that performs well on social media. Our 'TikTok Viral' preset automatically applies these optimized settings for you.

Can I use the processed audio in my social media content?

While our tool enables you to create slowed & reverb versions, please remember that the original copyright of songs remains with the artists and rightsholders. For personal use, there are typically no issues. For commercial or monetized content, you should obtain proper licenses for the original music. Many creators use these effects for personal content on platforms like TikTok, Instagram Reels, and YouTube Shorts.
