| Format Overview |
TTA
True Audio
True Audio (TTA) is a free, open-source lossless audio codec created in 2004. It uses a simple adaptive prediction filter followed by entropy coding to achieve lossless compression ratios comparable to FLAC and APE. TTA is designed for simplicity and speed, offering real-time encoding and decoding with minimal CPU usage, making it well suited for hardware players and embedded devices. Lossless Modern |
DTS
Digital Theater Systems
DTS (Digital Theater Systems) is a surround sound audio codec originally developed for cinema in 1993. DTS Core encodes up to 5.1 channels at bitrates up to 1.5 Mbps, delivering higher audio quality than AC3 at the cost of larger file sizes. DTS is standard on Blu-ray discs, and its extensions support lossless audio and immersive 3D sound. Lossy Standard |

| Audio Encoding |
TTA uses an adaptive prediction filter that models audio signals and encodes residuals with Rice/Golomb entropy coding for bit-perfect lossless compression: # Encode WAV to TTA lossless ffmpeg -i input.wav -codec:a tta output.tta # Encode with specific sample format ffmpeg -i input.wav -codec:a tta \ -sample_fmt s16 output.tta |
DTS uses subband ADPCM coding with psychoacoustic modeling for high-quality multichannel surround sound: # Encode to DTS Core ffmpeg -i input.wav -codec:a dca \ -b:a 1411k output.dts # Stereo DTS at lower bitrate ffmpeg -i input.wav -codec:a dca \ -b:a 768k -ac 2 output.dts |

Why Convert TTA to DTS?
Converting TTA to DTS transforms your lossless True Audio files into the widely compatible Digital Theater Systems format. This is a lossy conversion that permanently reduces audio data to achieve smaller file sizes. The trade-off between file size and quality makes DTS ideal for portable playback, streaming, and distribution where storage and bandwidth are limited.
TTA preserves every sample of the original recording through lossless compression, resulting in larger files that maintain full audio fidelity. By converting to DTS, you significantly reduce file sizes while retaining perceptually transparent quality at reasonable bitrates. This makes your music collection practical for mobile devices, streaming, and sharing.
The conversion process decodes the TTA lossless stream back to raw PCM audio, then re-encodes it using the DTS codec. Since TTA is lossless, the DTS encoder receives the full-quality original signal, ensuring the best possible lossy encoding result equivalent to encoding directly from an uncompressed WAV source.
Keep your original TTA files as master archives whenever possible. Converting TTA to DTS is a one-way quality reduction that cannot be reversed to recover the original lossless quality. Use DTS copies for everyday listening and distribution while preserving TTA originals for future re-encoding needs.
Key Benefits of Converting TTA to DTS:
- Smaller Files: Significantly reduced file size compared to lossless TTA originals
- Device Compatibility: DTS plays on virtually all devices and platforms
- Optimal Encoding: Lossless TTA source provides the best possible input for DTS encoding
- Portable Playback: Practical file sizes for phones, tablets, and portable players
- Streaming Ready: DTS files are ideal for streaming and web distribution
- Batch Processing: Convert entire TTA libraries to DTS for everyday listening
- Preserve Originals: Keep TTA masters for archival while using DTS for daily use
Practical Examples
Example 1: Portable Music Collection
Scenario: A music enthusiast wants to create a portable copy of their TTA lossless library for use on a smartphone with limited storage.
Source: favorite_album.tta (55 min, 16-bit/44.1 kHz, 380 MB) Conversion: TTA → DTS Result: favorite_album.dts (~55 MB at high quality) Workflow: 1. Convert TTA → DTS for mobile playback 2. Transfer DTS files to smartphone 3. Enjoy music at 1/7 the file size 4. Original TTA preserved on home server 5. Re-encode from TTA if different quality needed
Example 2: Music Sharing and Distribution
Scenario: A musician needs to share demo tracks with fans. The original recordings are in TTA format, too large for email and messaging.
Source: demo_song.tta (4 min, 24-bit/48 kHz, 65 MB) Conversion: TTA → DTS (high quality) Result: demo_song.dts (~6 MB) Benefits: - Small enough to share via email or messaging - Plays on any device without special software - High-quality encoding from lossless TTA source - Quick conversion thanks to TTA's fast decoding - Universal DTS playback compatibility
Example 3: Podcast Feed Preparation
Scenario: A podcast producer records and masters in TTA lossless but needs to publish in DTS for podcast directories and RSS feeds.
Source: episode_042.tta (60 min, 16-bit/44.1 kHz, 420 MB) Conversion: TTA → DTS Result: episode_042.dts (~42 MB) Distribution requirements met: - Podcast-directory-compatible DTS format - Reasonable file size for RSS download - Best encoding quality from lossless master - Consistent audio quality across episodes - TTA masters archived for future remastering
Frequently Asked Questions (FAQ)
Q: Does converting TTA to DTS lose any audio quality?
A: Yes. DTS is a lossy format, so some audio data is permanently discarded during encoding. However, since TTA is lossless, the DTS encoder receives the full-quality original signal, producing the best possible result.
Q: Will the file size change after converting TTA to DTS?
A: Yes. DTS files are significantly smaller than TTA because lossy compression removes audio data. Expect roughly 60-90% size reduction depending on the DTS bitrate setting.
Q: Why convert from TTA to DTS instead of another format?
A: DTS (Digital Theater Systems) offers broad device compatibility, smaller file sizes, and wide platform support ideal for portable playback and sharing.
Q: Is TTA a good format for archival purposes?
A: TTA is an excellent archival format providing bit-perfect lossless compression with fast encoding speed. However, FLAC has a larger ecosystem for long-term archival. TTA's advantage is its simplicity and processing speed for large-scale batch tasks.
Q: Can I convert TTA back to DTS after converting DTS to TTA?
A: You can re-encode from TTA, but each lossy encode introduces new artifacts. Always encode from the highest-quality source and keep TTA lossless files as masters.
Q: What software can play TTA files?
A: TTA is supported by foobar2000, VLC, AIMP, Deadbeef, and Rockbox-based portable players. While not as universal as FLAC, TTA has good coverage among enthusiast-oriented music software.
Q: How fast is the TTA to DTS conversion?
A: TTA decodes very quickly due to its simple algorithm, typically 10-20x faster than real-time. The overall speed depends on the DTS encoding complexity. Most files convert in seconds on modern hardware.
Q: Can I batch convert my entire TTA library to DTS?
A: Yes. Batch conversion is fully supported. Our converter processes each TTA file individually, converting it to DTS with your chosen settings. TTA's fast decoding makes batch conversion of large libraries efficient.
