What is VCM Vocal Delay?
VCM Vocal Delay is a free online vocal delay effect that runs entirely in your browser. Whether you're adding subtle depth to a vocal take or creating dramatic stereo echoes, this tool gives you professional-grade BPM-synced delay without installing any plugins.
Sync your delay to any tempo from 40–240 BPM, choose between 1/4, 1/8, or 1/16 note divisions, dial in the perfect feedback and mix, and toggle ping-pong mode for stereo bounce effects. Preview your settings in real-time and export a high-quality WAV file when you're happy with the result.
All processing happens locally on your device—your audio is never uploaded to any server. Perfect for quick vocal processing, demo production, or experimenting with delay effects without the complexity of a full DAW setup.

Frequently Asked Questions
What is ping pong delay?
Ping pong delay bounces the delayed signal between the left and right stereo channels, creating a wide, immersive sound where echoes alternate from side to side.
What BPM should I use for my delay?
Match the BPM of your song. If your track is at 120 BPM, set the delay to 120 BPM. This ensures the delay repeats are perfectly in time with the music.
What's the difference between 1/4, 1/8, and 1/16 note delays?
1/4 note delay is the longest (one beat), 1/8 is half that speed (half beat), and 1/16 is the fastest (quarter beat). Faster divisions create tighter, more rhythmic echoes.
How do I create a slapback delay?
For slapback, use a faster division like 1/16, set feedback low (10-20%), and mix around 20-30%. This creates a quick, single-repeat echo popular in rockabilly and country vocals.
Why does high feedback cause runaway sound?
High feedback means each echo is nearly as loud as the previous one. VCM Vocal Delay caps feedback at 95% to prevent infinite buildup while still allowing long, atmospheric trails.
Is my audio stored on your servers?
No. All audio processing happens directly in your browser using the Web Audio API. Your files never leave your device.
What file types are supported?
VCM Vocal Delay supports WAV, MP3, and M4A files. For best quality, we recommend uploading WAV files.
Can I export wet-only audio?
Set the Mix slider to 100% to hear only the delayed (wet) signal. The export will match your current Mix setting.
Why does the exported file include extra silence at the end?
The extra time is the delay tail—it allows the echo repeats to fade out naturally instead of cutting off abruptly.
Can I use this on mobile devices?
Yes, VCM Vocal Delay works on most modern mobile browsers that support the Web Audio API, including Safari on iOS and Chrome on Android.
