Advanced mode in TNT Plus
Configure encoding parameters, loudness targets, and processing options.
Format Selection
Choose AAC, Opus, MP3, PCM (WAV), or FLAC.
Sample Rate (PCM only): 44.1-192 kHz Bit Depth (PCM only): 16, 24, 32-float, 64-float Bitrate (AAC, Opus, MP3): 12 kbit/s minimum, encoder-specific maximum Compression Level (FLAC, Opus): 0 (no compression) to 10 (maximum compression)
Loudness targets
Target (LUFS) and TP limit (dB) control loudness processing for normalization and ReplayGain tagging.
Custom Loudness: Configure custom LUFS I and TP targets. Values convert to negative automatically. When disabled, uses EBU R128 defaults (-23 LUFS, -1 dBTP) if Normalize is selected.
Processing Options
Normalize: Applies loudness correction using BS.1770-5 algorithm
- Uses custom values (Custom Loudness enabled) or EBU R128 standard (disabled)
- Alters audio data to match target loudness
Write RG tags: Writes ReplayGain metadata to audio files
- Uses custom values (Custom Loudness enabled) or EBU R128 defaults
- Writes metadata only; does not alter audio data
- Cannot be used with Normalize
- Not available for PCM source files
Do not transcode: Preserves original audio encoding while writing tags
- Available only when Write RG tags is enabled
- Writes metadata only; does not alter audio data
- Not available for PCM source files
Speech: Optimizes encoding for voice content
- If Opus is selected, applies VoIP-optimized compression
- Uses speech-specific normalization when combined with Normalize
- Not for music content
