| Format Overview |
TTA
True Audio Lossless Codec
True Audio (TTA) is a free, open-source lossless audio codec that achieves compression ratios similar to FLAC while offering real-time encoding and decoding with minimal CPU usage. TTA uses adaptive prediction and entropy coding to compress audio losslessly, making it popular among audiophiles seeking an efficient alternative to FLAC. Lossless Modern |
W64
Sony Wave64
Sony Wave64 is an extended audio container format that overcomes the 4 GB file size limitation of standard WAV/RIFF. Developed by Sony's Sonic Foundry division for use in Sound Forge and Vegas Pro, W64 uses 64-bit addressing based on GUIDs (Globally Unique Identifiers) to support files of virtually unlimited size. It stores uncompressed PCM audio identical to WAV but in a container designed for professional long-form recording and multichannel production. Lossless Standard |

TTA uses adaptive linear prediction with Rice entropy coding for fast, efficient lossless compression: # Encode to TTA lossless ffmpeg -i input.wav -codec:a tta \ output.tta # TTA from high-resolution source ffmpeg -i input.wav -codec:a tta \ -ar 96000 output.tta |
W64 stores raw PCM samples using 64-bit chunk headers based on GUIDs, eliminating the 4 GB barrier of standard RIFF/WAV: # Convert audio to W64 format ffmpeg -i input.wav -codec:a pcm_s24le \ output.w64 # High-resolution W64 (32-bit float, 96 kHz) ffmpeg -i input.wav -codec:a pcm_f32le \ -ar 96000 output.w64 |

Why Convert TTA to W64?
Converting TTA to W64 transforms your True Audio Lossless Codec files into Sony Wave64 format, an extended audio container that overcomes the 4 GB file size limitation of standard WAV. W64 uses 64-bit GUID-based addressing to support files of virtually unlimited size, making it essential for long-form professional recordings, multichannel sessions, and high-resolution audio production.
TTA provides lossless audio, and converting to W64 preserves the original quality while providing an uncompressed PCM container without size limits. This is particularly important when working with recordings that approach or exceed the 4 GB boundary of standard WAV files.
Sony Wave64 was developed by Sonic Foundry (later acquired by Sony) specifically for professional audio production where standard WAV's 4 GB limit becomes a constraint. A single 24-bit/96 kHz stereo WAV file reaches 4 GB in just 3.7 hours, while multichannel recordings hit this limit much sooner. W64 removes this barrier entirely, allowing uninterrupted recording sessions of any duration.
This conversion is ideal for audio professionals working in Sony Vegas Pro, Sound Forge, or REAPER who need unrestricted file sizes for importing TTA content into professional production environments. W64 is also supported by FFmpeg and libsndfile, ensuring compatibility with automated processing pipelines and batch conversion workflows.
Key Benefits of Converting TTA to W64:
- No Size Limit: W64 removes the 4 GB file size barrier of standard WAV
- Uncompressed PCM: Bit-perfect audio storage with zero quality loss
- Sony DAW Integration: Native support in Sony Vegas Pro and Sound Forge
- Long-Form Recording: Record sessions of unlimited duration at any resolution
- Multichannel Support: Handle unlimited channel counts for surround production
- Quality Preservation: Lossless TTA source is decoded to uncompressed W64 with no quality loss
- Professional Standard: W64 meets professional production requirements for high-resolution audio
Practical Examples
Example 1: Long-Form Recording Session
Scenario: A studio engineer needs to import TTA audio files into a Sony Vegas Pro project for a 4-hour documentary soundtrack that will exceed the 4 GB WAV file limit.
Source: documentary_audio.tta (4 hours of source material) Conversion: TTA → W64 Result: documentary_audio.w64 Workflow: 1. Convert TTA source material to W64 format 2. Import W64 into Sony Vegas Pro timeline 3. Edit and mix without 4 GB size concerns 4. Record additional voiceover directly in W64 5. Export final mix as needed
Example 2: Multichannel Surround Production
Scenario: An audio post-production house receives TTA files for a multichannel surround mix. They need W64 for unrestricted file sizes during the mixing session in Sound Forge.
Source: surround_stems_*.tta (6 channels of audio) Conversion: TTA → W64 Result: surround_stems_*.w64 Benefits: ✓ No file size limit for multichannel recordings ✓ Native compatibility with Sound Forge ✓ Uncompressed PCM for transparent editing ✓ GUID-based format prevents chunk conflicts ✓ Ready for extended mixing sessions
Example 3: Audio Archive Migration
Scenario: A music library with hundreds of TTA files needs to be migrated to W64 for a production house that standardized on Sony Wave64 for their post-production pipeline.
Source: music_library/*.tta (500+ files) Conversion: TTA → W64 (batch processing) Result: music_library/*.w64 Migration plan: ✓ Batch convert entire TTA library to W64 ✓ Verify audio integrity with checksum comparison ✓ Integrate W64 files into Sony-based production pipeline ✓ Maintain original TTA files as backup
Frequently Asked Questions (FAQ)
Q: Why convert TTA to W64 instead of regular WAV?
A: W64 (Sony Wave64) uses 64-bit addressing to support files larger than 4 GB, which standard WAV cannot handle due to its RIFF 32-bit container limitation. If your TTA audio will exceed 4 GB (common with long recordings, high sample rates, or multichannel audio), W64 is the appropriate uncompressed format.
Q: Does converting TTA to W64 improve audio quality?
A: Since TTA is already lossless, converting to W64 preserves identical quality — both formats are bit-perfect.
Q: What software supports W64 playback?
A: W64 is natively supported by Sony Vegas Pro, Sound Forge, REAPER, Adobe Audition, and Audacity. VLC, foobar2000, and AIMP can also play W64 files. FFmpeg and libsndfile provide library-level support for custom applications.
Q: How much larger will the W64 file be compared to TTA?
A: W64 stores uncompressed PCM, so files will be approximately 2x larger than TTA lossless files, which use compression to reduce size.
Q: Is W64 compatible with all DAWs?
A: While W64 has broader support than many expect (Sony Vegas, Sound Forge, REAPER, Audacity, Adobe Audition), it is not as universal as WAV. Pro Tools and Logic Pro may require conversion to WAV or AIFF. If your recordings do not exceed 4 GB, standard WAV provides maximum DAW compatibility.
Q: Can I convert W64 back to TTA later?
A: Yes — W64 stores uncompressed audio, so you can convert to any format at any time. The round-trip from TTA to W64 and back will be bit-perfect since both formats are lossless.
Q: What is the maximum file size for W64?
A: W64 uses 64-bit addressing, theoretically supporting files up to 16 exabytes — effectively unlimited for any practical audio recording. This is the primary advantage over standard WAV, which is limited to approximately 4 GB (about 6.75 hours of 16-bit/44.1 kHz stereo audio).
Q: When should I choose W64 over other lossless formats like FLAC?
A: Choose W64 when you need uncompressed PCM audio without size limits, particularly for Sony Vegas Pro or Sound Forge workflows. FLAC offers 50-70% smaller files through lossless compression but adds encoding/decoding overhead. W64 is best for active recording sessions and production, while FLAC is better for archival and distribution.
