What is AU file size reducer?

At ezyZip, we offer an advanced compression feature that allows you to reduce the size of your AU files either by setting a specific target file size or by selecting a percentage reduction. This functionality is perfect for tailoring AU files to meet various requirements or limitations. Whether you need to comply with size constraints for uploads and emails, or simply want to save disk space, you can easily customize the compression to fit your needs.

Will sound quality be impacted when I reduce AU file size?

Yes, reducing the size of an audio file will likely impact the audio quality. AU files use a audio compression algorithm that discards certain parts of the audio data to decrease file size—a process known as "lossy" compression. When you further reduce the audio bitrate, the compression becomes more aggressive, which means more audio information is removed. This generally results in a decrease in sound quality, characterized by a reduction in clarity, depth, and fidelity. The extent of quality loss depends on your desired output file size and the specific compression settings used during the conversion process.

The ezyZip audio compressor will select optimal audio bitrate and codec to ensure it closely matches original quality.

Once the compression process is complete, ezyZip offers a feature to "preview" the audio file before saving to see if it meets your quality requirements.
