"The issue you’re experiencing with NCH Voxal—hearing your own voice played back with a delay—commonly occurs due to feedback loops or incorrect audio configuration, often related to the "Listen to this device" setting or audio driver conflicts. This kind of problem can make real-time voice changing unusable. Here’s how to address it:
Primary Causes and Solutions:
Check the Microphone “Listen” Setting: If you have enabled the Windows setting to "Listen to this device" for your microphone, it will cause your voice (changed or not) to play back to you with a delay. Open the Windows Sound settings:
- Go to Sound settings > Recording tab.
- Right-click your microphone, select Properties, and then go to the Listen tab.
- Ensure "Listen to this device" is unchecked.
Correct Input/Output Assignment: In Voxal, make sure the Input device is your microphone and the Output device is set either to your system speakers or headphones, avoiding “Voxal” as both input and output, which can lead to a feedback loop.
Device Configuration Order: Always start Voxal before the program you intend to use it with (e.g., Discord, Skype). Closing and reopening both applications in the correct order can resolve communication and effect issues.
Reduce Audio Effects Chain: Applying too many effects can overburden your system and result in lag or distorted sound. Try removing some effects to see if latency and feedback issues improve.
Audio Driver Issue & Reinstallation: Uninstalling and reinstalling your audio drivers may help, as driver conflicts can cause repeated audio playback and recognition errors.
Check for Updates and Compatibility: Ensure both Voxal and your audio drivers are fully updated. Occasionally, specific effects (such as the Voice Pitch Shifter) can cause persistent errors in particular software versions, which might only be resolved in later updates.
If the Issue Persists:
Try a different microphone to rule out hardware compatibility issues (some USB mics or audio interfaces have known issues with Voxal).
Reinstall Voxal, ensuring a clean install and a restart after installation.
If using "record and listen" preview mode, switch to a different preview mode or disable preview entirely if not needed.
If none of these steps work, consider submitting a support ticket with NCH, as persistent feedback issues may indicate a software bug that requires direct troubleshooting by the developers.
Important: Unintentional audio routing—especially with "Listen to this device" or selecting the wrong input/output devices—accounts for most constant voice playback issues with delay. Always verify these settings first."
