Common Issues & Solutions

File Upload Issues

File too large

Maximum file size: Free tier 10MB, Basic/Pro plans 100MB, Premium plan 200MB. Large files are automatically processed in chunks to prevent browser crashes. Upgrade to Premium for larger files.

Unsupported format

Supported formats: MP3, WAV, M4A, AAC, OGG, FLAC. Convert your file to one of these formats.

Upload fails

Check your internet connection and ensure your browser supports modern web standards.

Processing Problems

No silence detected

Lower the threshold (try -45dB or -50dB) or reduce minimum duration settings.

Too much audio removed

Raise the threshold (try -35dB or -30dB) or increase minimum duration to preserve intentional pauses.

Processing stalls

Refresh the page and try again. For large files, processing may take a few moments.

Audio Quality

Choppy playback

Ensure stable internet connection and try refreshing the page. Preview uses temporary processing.

Quality loss

The tool preserves original quality. Quality issues usually stem from the source recording.

Unexpected cuts

Adjust minimum duration settings to prevent removal of short but important audio segments.

Payment & Download

Payment fails

Check card details, ensure sufficient funds, or try a different payment method.

Download doesn't start

Check browser popup blockers and ensure JavaScript is enabled. Try refreshing the page.

File corrupted

Re-download the file. If issues persist, contact support with your transaction details.

Frequently Asked Questions

How does Voice Trimmer work?

Voice Trimmer uses advanced Web Audio API technology to analyze your audio files in real-time. It detects silence based on RMS (Root Mean Square) levels and removes dead air while preserving the natural flow of your content. All processing happens in your browser for complete privacy.

Is my audio data safe?

Absolutely. Your audio files never leave your device. All processing happens locally in your browser using JavaScript and Web Audio API. We only handle payment processing through secure Stripe checkout - your audio content remains completely private.

What audio formats are supported?

We support all major audio formats including MP3, WAV, M4A, AAC, OGG, and FLAC. The output format matches your input format to ensure compatibility and quality retention.

Can I adjust how much silence is removed?

Yes! You can customize the silence threshold from -60dB to -20dB and set minimum silence duration from 0.1 to 2.0 seconds. This allows you to fine-tune the processing for your specific recording environment and content type.

What if I'm not happy with the results?

You can preview the results before payment. Adjust the settings and re-process as many times as needed until you're satisfied. We only charge when you download the final processed file.

Do you offer refunds?

Due to the digital nature of our service and the ability to preview results before payment, we don't offer refunds after download. However, you can preview and adjust settings unlimited times before purchasing.

What is Smart Detection?

Smart Detection is a Premium feature that uses advanced speech analysis to automatically improve silence removal and keep natural speech flow. It enhances the standard silence detection by identifying speech segments more accurately, resulting in better preservation of natural pauses and improved audio quality. This feature is available exclusively in the Premium plan.
