Audio compression is a fundamental production tool that balances the loudest and quietest parts of an audio signal, making the overall sound more cohesive and consistent.

Dynamic range is the difference between the quietest and loudest parts of an audio file. An audio compressor automatically lowers the volume when the sound exceeds a certain threshold, then raises the overall gain, making quiet details audible while keeping loud peaks in check. This is crucial for podcast vocals and vocal tracks in music, ensuring listeners don't have to constantly adjust their volume.

Our compressor features three optimized presets for different use cases: - **Light Compression (Low)**: Features a high threshold and low ratio (2:1). Perfect for maintaining natural dynamics in high-quality music tracks. - **Balanced (Medium)**: A general-purpose setting (4:1 ratio) that fits standard audio leveling. - **Maximum (High)**: Uses a very low threshold and high ratio (12:1) for aggressive leveling, ideal for smoothing out voice recordings, dictations, or noisy environments.

Traditional compression services require uploading files to remote servers, which takes time and compromises privacy. Our tool runs completely in your web browser. Utilizing the Web Audio API's DynamicsCompressorNode, the audio buffer is processed locally and exported straight to MP3. Your files never leave your computer.
