- **Silence Threshold (dB)** (number): -50
- **Max Silence Duration (s)** (number): 2.0
- **Output Format** (select)

## When to use

- When preparing audio for presentations or videos to maintain listener engagement.
- When cleaning up recorded interviews or lectures to reduce file size and enhance clarity.

## How it works

- Upload your audio file in a supported format like MP3, WAV, or AAC.
- Adjust the silence threshold in decibels (dB) to define what audio level counts as silence.
- Set the maximum allowed silence duration in seconds to truncate longer pauses.
- Select your preferred output format, such as MP3 or FLAC, and process the file to download the trimmed audio.

## Use cases
