DFF vs TTA
Um comparativo detalhado de DSD Interchange File e True Audio Lossless — tamanho de arquivo, qualidade, compatibilidade e qual escolher de acordo com seu fluxo de trabalho.
DSD Interchange File
Audio FilesDFF (DSDIFF - DSD Interchange File Format) is the original file format for DSD audio data, developed by Philips. Unlike DSF, it uses a chunked IFF structure and is the native format for many professional DSD recording systems.
Sobre os arquivos DFFTrue Audio Lossless
Audio FilesTTA (True Audio) is an open-source lossless audio codec that provides real-time lossless compression with hardware-friendly decoding. It achieves compression ratios similar to FLAC while maintaining very low CPU requirements during playback.

Perguntas frequentes
DFF (DSD Interchange File) is an audio file format used to store sound recordings — music, voice, podcasts, sound effects. The format defines how the audio samples are compressed (or stored raw), what bitrates are supported, and how metadata such as title, artist, album, and cover art is embedded. It is part of the audio files family.

VLC, foobar2000, and the default media players on Windows and macOS handle DFF natively. On mobile, iOS Music and Android media apps vary in their support — popular formats work everywhere; niche ones may need a dedicated app. If playback fails on a device, converting to MP3 or AAC usually solves it.

Upload the DFF to KaijuConverter and pick MP3, WAV, FLAC, AAC, OGG, or any other target. Our FFmpeg pipeline decodes the audio and re-encodes to the target format at sensible default bitrates (VBR ~190 kbps for music, 96 kbps for speech). Metadata and cover art travel with the audio where both formats support them.
DFF can be lossy or lossless depending on the specific variant. Lossy variants (smaller files) discard some audio detail during compression in ways tuned to be inaudible; lossless variants preserve every sample exactly but produce larger files. For distribution, lossy at high bitrate is standard; for archival, lossless wins.
