A Complete Audio Workflow in Your Browser
A typical end-to-end audio task on UDT goes through several of these tools in a chain. You record a podcast episode in three takes, plus an intro music bed. You want to ship a single mastered file at a loudness target that won't get adjusted by Apple Podcasts or Spotify. Six tools, one continuous workflow.
Start with the Audio Trimmer on each take — set in and out points to drop silence and verbal flubs. Then run each take through the Audio Silence Remover to auto-shorten the breath gaps inside the recording — a 60-minute take usually drops to around 52. Drag the trimmed clips plus the intro bed into the Audio Merger, reorder until the sequence is right, and pick a crossfade duration (250ms for voice-to-voice, 1–2 seconds for music-to-voice).
Once the merged episode is together, add a polish pass with the Audio Fade tool — a 2-second fade-in at the start, a 3-second fade-out at the end. Then run the Audio Normalizer with the Spotify or Apple Music preset (depending on where the episode will land first), and finish with the Audio Peak Limiter at -1dB ceiling — limit-after-normalize is the standard mastering chain and catches any transients the loudness boost pushed near the ceiling. Finally, compress to MP3 at 128kbps with the Audio Compressor using the Podcast Music preset.
Other common chains: extract audio from a recorded video interview with the Audio Extractor, then run the MP3 through the Audio Transcription tool for show-notes prep (downsample first to 16kHz with the Audio Sample Rate Converter to speed up the Whisper run). Convert a FLAC archive to MP3 for portable playback via the Audio Converter. Trim a 30-second song segment with the Audio Trimmer, transpose to a singable key with the Audio Pitch Shifter, slow it down 10% for practice with the Audio Tempo Changer, fade both ends with the Audio Fade tool, and you have a custom ringtone or backing track. Split a dual-mic stereo podcast recording into left and right mono files for individual editing with the Audio Channel Tool.
The point of grouping these as a suite rather than just listing them is that every tool's output naturally becomes another tool's input. Pick the tool that matches your immediate next step; chain as far as your task demands.
