3 tools Format & Compression
001Audio CompressorShrink an audio file by re-encoding it to MP3, AAC, or Opus. Set a bitrate or a target size in megabytes, downsample or downmix to mono, and read the estimated output before the export runs.002Audio ConverterConvert audio between WAV, MP3, M4A, Ogg Opus, and FLAC. Reads MP3, WAV, FLAC, M4A, AAC, Ogg, Opus, and WebM audio, and keeps the source sample rate and channel count.003Audio Sample Rate ConverterResample an audio file to 44.1, 48, 22.05, 16 kHz, or another delivery rate, downmix it to mono, and export it as WAV, FLAC, MP3, M4A, or Ogg Opus.

6 tools Editing
004Audio Channel ToolSum a stereo file to mono, swap left and right, send one side to both channels, isolate the difference between them, or flip the phase of a single channel, then write the result as stereo or as a single-channel file.005Audio MergerJoin several audio files into one, in the order you set. Sources with different sample rates or channel counts are matched to the highest of the set, and each seam is faded so a join does not click.006Audio Silence RemoverFind the silent gaps in a recording and cut them out, keeping a set amount of pause at each edit. Set the level that counts as silence, the shortest gap worth removing, and how much to leave behind.007Audio Speed ChangerPlay an audio file from 0.1x to 10x its original speed and keep the pitch where it was, or let pitch rise and fall with tempo the way a tape machine does.008Audio SplitterCut one audio file into equal parts or into fixed-length pieces and download them as a ZIP. Every piece keeps the source format and is cut on an exact boundary.009Audio TrimmerCut a section out of an audio file by dragging a range across the waveform, check the boundaries with looped playback, and export that range in the format the source arrived in.

17 tools Level & Tone
010Audio Bass BoosterRaise the low end of an audio file with a shelf between 40 and 250 Hz, remove everything under a chosen corner first so nothing subsonic gets amplified, and generate an octave below the band when the recording has nothing down there to raise.011Audio De-esserCompress only the sibilant band of a vocal recording. Set the crossover frequency between 2 and 14 kHz, a threshold, and how many dB the harsh band is allowed to fall, in split band or wideband mode.012Audio DenoiserReduce steady background hiss, hum, and room tone with a noise floor that keeps adapting as the file plays.013Audio EqualizerThree-band EQ with a low shelf from 30 to 250 Hz, a mid bell sweepable from 100 Hz to 10 kHz with adjustable width, and a high shelf from 2.5 to 16 kHz, each across ±18 dB.014Audio ExciterGenerate harmonics from the band above a corner frequency and add them over the original signal. Set the frequency between 1 and 12 kHz, the amount, and whether the added harmonics are odd or even order.015Audio Fade In and OutAdd a fade-in at the start and a fade-out at the end of an audio file, with a linear, equal-power, or exponential curve and lengths up to 30 seconds each.016Audio Filter (Low-Pass and High-Pass)Run an audio file through a low-pass, high-pass, band-pass, or notch filter with a log cutoff sweep from 20 Hz to 20 kHz, adjustable resonance, 12 or 24 dB/octave, and a wet/dry mix.017Audio Hum RemoverNotch out mains hum at 50 or 60 Hz along with up to four harmonics. Set the fundamental, how many harmonics to follow, the notch width, and how far each one drops.018Audio LimiterRaise the level of an audio file against a ceiling that peaks cannot cross, using 5 ms of lookahead, an input gain, and an adjustable release.019Audio Noise GateMute an audio file while it sits below a threshold, with hysteresis, hold, attack, release, and a range control that sets how far the closed gate attenuates.020Audio NormalizerMeasure a file to ITU-R BS.1770-4, then apply the gain that lands it on a loudness target such as -14 LUFS or on a true peak ceiling, with an optional limiter holding the peaks.021Audio Sidechain CompressorDuck an audio file's level on a rhythmic pulse, the pumping effect normally driven by a kick drum on a second track.022Audio Stereo WidthWiden or narrow the stereo image of an audio file from 0 to 200%, pan it with constant-power gains, and fold the side channel to mono below a crossover you set.023Audio Transient ShaperRaise or cut the attack and the sustain of a recording separately, with no threshold to set. Two envelope followers compare fast and slow level, and the difference between them drives the gain.024Audio Volume ChangerRaise or lower the level of an audio file by a set number of decibels, compare the result against the original while it plays, and export it in the format the source arrived in.025Dynamic Range CompressorCompress the dynamic range of an audio file with threshold, ratio, knee, attack, release, and makeup gain, and hear the result before exporting.026Multiband CompressorCompress low, mid, and high bands on separate thresholds. Set the two crossover points, one threshold per band, then a shared ratio, attack, release, and makeup gain.

16 tools Effects
027Audio AutopanSweep an audio file's stereo image left and right at a set rate using constant-power panning, with sine, triangle, or square shapes.028Audio BitcrusherReduce an audio file to between 1 and 16 bits and divide its sample rate by up to 64, with a wet/dry mix, for quantisation noise and aliasing.029Audio ChorusAdd a chorus effect to an audio file with up to 3 modulated voices, a 0.05 to 5 Hz rate, depth in milliseconds, stereo spread, and a wet/dry mix.030Audio DistortionApply soft clip, hard clip, or foldback distortion to an audio file, with drive, a post-shaper tone filter from 400 Hz to 12 kHz, and wet/dry mix.031Audio EchoAdd delay-based echo to an audio file, with delay times from 10 ms to 2000 ms, adjustable feedback, wet/dry mix, and ping-pong bouncing between stereo channels.032Audio FlangerAdd a flanger to an audio file with a sweeping sub-10 ms delay, positive or negative feedback up to 90%, adjustable base delay, stereo phase offset, and a wet/dry mix.033Audio HarmonizerLayer two pitch-shifted voices at musical intervals under or over an audio file to build harmony automatically.034Audio PhaserAdd a phaser to an audio file with 2 to 8 all-pass stages, a logarithmic sweep from 200 Hz, feedback up to 80%, and a wet/dry mix.035Audio Pitch ShifterShift pitch by up to 12 semitones plus 50 cents of fine tune while the file keeps its exact length. Every partial moves by the same ratio, so the result lands under a cent from the target note.036Audio ReverbAdd reverb to an audio file with controls for room size, damping, pre-delay, and wet/dry mix. The export continues past the end of the source so the decay finishes.037Audio TremoloModulate the level of an audio file from 0.1 to 20 Hz with sine, triangle, or square shapes, adjustable depth, and a stereo phase offset for auto-pan.038Audio VibratoModulate the pitch of an audio file from 0.1 to 12 Hz with adjustable depth in milliseconds, a stereo phase offset, and a wet/dry mix.039Audio Vinyl SimulatorAdd turntable pitch wobble, surface crackle, and a rolled-off top end to an audio file for a lo-fi vinyl character.040Auto-WahSweep a resonant band-pass filter with the level of the signal itself. Set sensitivity, the base frequency, how many octaves the sweep covers, resonance, release, and the wet/dry mix.041Ring ModulatorMultiply an audio file by a carrier tone from 5 Hz to 4 kHz with sine, triangle, or square shapes, a stereo phase offset, and a wet/dry mix.042Rotary SpeakerRun audio through a spinning horn and drum cabinet with a shared rate from 0.1 to 8 Hz, a depth control for the pitch and level swing, stereo width, and a wet/dry mix.
