MP3 is a audio format: it applies psychoacoustic lossy compression to remove frequencies the human ear perceives least, producing small files at acceptable audio quality. DTS is a audio format that stores data in the DTS format. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. Converting between these two formats is common when the source application does not support DTS natively or when the target platform only accepts DTS. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
