How audio encoders use psychoacoustic masking to reduce file sizes, and why this process creates audible artifacts in compressed formats.
Understanding what is loudness, how it's measured and why standards exist.
Understanding bit depth, quantization and why float sample rates are needed.
How randomization helps to alleviate the effects of quantization.
TNT is designed for broadcast professionals to streamline audio workflows. The application provides three core capabilities:
• Transcode - Convert between audio formats
• Normalize - Ensure consistent loudness levels
• Tag - Write ReplayGain metadata for playback guidance
Simple mode offers three preset configurations for common use cases. Processing requires just four clicks, and files are processed individually in the background with results appearing in your output folder as they complete.
Advanced mode provides granular control over encoding parameters including format selection, sample rates, bit depths, and bitrates. You can configure custom loudness normalization targets or write ReplayGain tags instead of normalizing.
Note: Normalization alters the audio data, while tagging only writes metadata. These options are mutually exclusive.
