Song studio

Processing uses the selected audio. Filters use frequency; EQ also uses gain and Q (band width); dynamics use threshold. Compression links stereo channels. The limiter applies an immediate peak ceiling. For noise repair, capture a noise-only passage, then select the audio to clean. Sensitivity boosts the measured noise power; higher values remove more signal. Smoothing spreads gains over neighboring FFT bands; 0 disables it. Listen to removed noise to check what would be lost. A/B previews restart at the same selection start, up to five seconds, with short audition fades and no automatic level matching. Apply commits the full selection with Undo available. Noise profiling and reduction support up to 30 seconds.

Positive tempo makes audio shorter; −50% doubles its duration and +100% halves it. Pitch totals −12 to +12 semitones, including cents. Input: up to 30 seconds; output: up to 60 seconds, within 64 MiB processing buffers. Select at least one FFT window. Larger windows favor sustained tones; smaller windows retain more timing detail. Transient protection resets phase at detected attacks. Experimental formant preservation estimates the broad spectral envelope and can color the sound; compare previews on your material. Preview starts at the selection beginning and plays up to five output seconds. Apply replaces only the selection, shifts following waveform audio, and keeps Undo. Stop or parameter changes cancel an unfinished render.

Click threshold is the minimum sample jump; lower values detect smaller spikes and may alter transients. Clipping threshold is the absolute peak level of damaged samples; set it to the recorded clipping level. Repairs use neighboring intact samples and keep duration. Gap repair needs a selection of 1–128 samples with two intact samples on each side. Automatic tools skip damage wider than the width limit or without intact boundaries. Reconstructed peaks can exceed full scale; lower gain before exporting. These estimates cannot recover the original lost recording. Maximum selection: 30 seconds.

The envelope spans the whole waveform. Gain 1 is unchanged, 0 is silence, 2 is twice the amplitude. Points interpolate linearly; the first and last gains extend to the edges. It is a draft until Apply renders the selected range and clears the draft. Undo restores both. Markers, regions and envelope drafts save in audio projects and follow time edits. Up to 256 labels and 128 points.

The rack processes effects from top to bottom. Edit loads a node into its effect panel; Update captures those controls. Rack edits and settings save with the waveform and support Undo. Preview renders from the current selected source and plays up to five seconds; rack export downloads the whole processed selection. Ordinary waveform playback and export use source PCM. Render replaces the selection and bypasses every rack effect in one Undo step. Changing the rack does not automatically alter an existing preview; preview again to hear it. Start with up to 30 seconds; output is limited to 60 seconds / 64 MiB, and each processor retains its own limits. Gap repair uses intact samples outside the selection. This is an offline rack, not a real-time insert chain.

Choose the family whose current controls you want to save. Saving the same name replaces that preset. Noise recipes include the captured noise profile. Repeat applies the last successful filter, noise, pitch/time or targeted repair to the current selection with Undo. Shortcut: Ctrl/⌘+R while the waveform has focus. Up to 32 presets.
