What is TTA?

True Audio (TTA) is a free, real-time lossless audio codec that provides efficient compression without compromising audio quality.

What is 3GA?

3GA (audio/3gpp) uses lossy compression optimized for mobile voice recordings, phone memos. 3GPP Audio, compressed audio from mobile phone recordings

When Should You Use TTA vs 3GA?

TTA vs 3GA: Key Differences

• •The core technical difference: TTA relies on lossless compression whereas 3GA uses lossy compression.
• •Moving from TTA (lossy) to 3GA (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: 3GA does not support alpha channels — transparent areas in the source will become opaque.
• •File sizes: TTA files typically range 40-50% smaller than WAV and 3GA files N/A.
• •Use case fit: TTA targets lossless audio compression, archival and 3GA targets mobile voice recordings, phone memos — your choice depends on which workflow stage you are serving.

Advantages of TTA

• ✓At its core, TTA relies on lossless encoding — a design choice that makes it perfect for Lossless audio compression, archival.
• ✓You won't run into compatibility issues with TTA — it's a universal standard across platforms.
• ✓File size management with TTA: larger files guaranteed to match the original exactly.
• ✓Every major application in the Lossless audio compression, archival space supports TTA natively.

Advantages of 3GA

• ✓3GA applies lossy compression specifically calibrated for Mobile voice recordings, phone memos.
• ✓3GA enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓3GA delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
• ✓You will find 3GA support built into virtually every tool that handles Mobile voice recordings, phone memos — no plugins or converters needed.

Troubleshooting TTA to 3GA Conversion

• !Clicks or pops in the converted 3GA → sample rate conversion can introduce artifacts; use a clean multiple of the source rate
• !3GA file has silence at the beginning or end → trim the source TTA file before converting to avoid unnecessary padding
• !Stereo image collapsed after converting TTA to 3GA → verify that the converter preserves channel mapping for multichannel audio
• !The converted 3GA clips or distorts at peaks → reduce the gain or apply a limiter before conversion to prevent hard clipping
