MIDI files store musical performances as data — notes, timing, velocity, and more — but that information is invisible unless you open the file in a DAW or similar software.

This tool unpacks your MIDI file and shows you what's inside: the key, tempo, note distribution, velocity dynamics, timing patterns, and how tightly the performance is quantized. It's useful for understanding a piece you downloaded, auditing your own work, or preparing a file before using it elsewhere.

Think of it like holding a printed score up to the light — the music is all there, this just makes it readable.

When you're working on a track, it can be hard to know how it stacks up technically — whether it's too quiet for streaming platforms, too dynamic, or clipping in ways that are hard to hear.

This tool reads your audio file and gives you a clear picture of its key measurements: loudness (LUFS), true peak level, RMS energy, and dynamic range. These are the same numbers engineers and mastering studios use to evaluate a mix.

Think of it like taking your car to a mechanic who hooks it up to diagnostics — you're not guessing anymore, you're reading the actual numbers.

This tool helps your track sound more polished by comparing it to a song you like and adjusting yours to match.

Instead of manually tweaking dozens of settings, it listens to both tracks and aligns things like tone, loudness, and overall balance so your music sits closer to a professional reference.

Think of it like tasting someone else's finished recipe, then adjusting your own dish until it has that same richness and balance.

Upload your track to see its loudness profile — integrated LUFS, true peak, dynamic range, and energy over time. Once analyzed, you can normalize the loudness to any streaming platform's target, or remove clipping if detected.

Think of it like a full diagnostic read before deciding what adjustments to make.

MIDI files contain the raw performance data for a piece of music — every note, its timing, and how hard it was played — but none of that is human-readable without software to interpret it.

This tool converts your MIDI file into standard musical notation, displayed as sheet music you can read, share, or import into notation software like MuseScore or Sibelius. The result renders directly in your browser and downloads as MusicXML, the format accepted by virtually every professional notation application.

Think of it like translating a player piano roll into written notation — the same music, made legible to anyone who can read a score.

WAV files are uncompressed audio — full quality, large file size. MP3 is a compressed format that trades a small amount of quality for dramatically smaller files, making it ideal for streaming, sharing, or embedding on a website.

This tool converts between WAV, MP3, FLAC, OGG, and AIFF. Upload your file, choose a target format, and download the result instantly. No quality settings to configure — conversions to WAV and FLAC always use 24-bit depth.

Think of it like changing a document between PDF and Word — same content, different container.

Every sound you hear is made up of frequency components changing over time. A spectrogram makes this invisible structure visible — revealing where energy is concentrated across the frequency spectrum, and how that evolves through the duration of a track.

Engineers use spectrograms to spot problem frequencies, check the high-end content of a mix, identify resonances, and understand the tonal fingerprint of a recording. Upload any audio file and see its full spectral portrait.

Think of it like an X-ray for audio — instead of bone and tissue, you see the harmonic content and texture of your music laid out across time and frequency.

A finished mix contains every instrument layered together into a single audio file. Sometimes you need to work with the individual parts — isolate the vocals to create an a cappella, extract the drums for a remix, or pull the bass out of a track you don't have the original session for.

This tool uses a state-of-the-art AI model to separate your audio into four stems: vocals, drums, bass, and other instruments. Each stem downloads as a separate WAV file at full quality.

Think of it like a prism for music, but instead of colors it splits the song into individual instruments and voices.

A 2-oscillator subtractive synthesizer built on the same principles as classic analog hardware like the Minimoog. Two oscillators generate raw waveforms, a resonant filter shapes the tone, and two ADSR envelopes control how the sound evolves over time.

Play the keyboard with your mouse, or load a MIDI file and press Play to hear it through the synth. Drag any knob up or down to adjust it. The Electrofunk Bass preset is tuned for that punchy 1980s funk and R&B sound.

Think of it like sculpting sound — you start with raw waves and carve away everything you don't want until only the tone you're after remains.

A faithful emulation of the Roland TR-808, the drum machine that defined hip-hop, techno, and electronic music. Every sound — kick, snare, hi-hats, toms, cowbell, clap, and cymbal — is synthesized live in your browser using the Web Audio API, no samples required.

Load a preset pattern or build your own by clicking the 16 steps in each row. Shift+click an active step to add an accent for a louder hit. Dial in BPM and swing, then export your loop as a MIDI file to drop straight into your DAW.

Think of it like the drum machine in every classic record you love — now in your hands.

Find the BPM of any song by tapping along — click the circle, tap your keyboard's Space bar, or touch the screen on mobile. The tool averages your last eight taps for a stable reading, then locks in a steady beat so you can keep playing without looking down.

Switch to Metronome mode to dial in an exact BPM and let the click track drive your practice. Beat 1 of every four pulses plays louder so you always feel the downbeat. Toggle the click sound on or off anytime — the visual ripple keeps the pulse even when silent.

Think of it as a conductor tapping a baton — except it learns your tempo and keeps it for you.

VST stands for Virtual Studio Technology — a plugin format created by Steinberg in 1996. A VST is a piece of software that runs inside your DAW to add virtual instruments, effects, and processors to your productions. Instead of buying physical hardware, you install a VST and it lives in your session like any other channel.

There are two core types. VST Instruments (VSTi) generate sound — synthesizers, samplers, drum machines, orchestral libraries, and any other virtual instrument you can think of. VST Effects process sound — compressors, EQs, reverbs, delays, saturators, and mastering tools. Most modern plugins ship in VST3 format (Windows and Mac), with AU versions for Mac-only hosts like Logic Pro.

Before VSTs existed, professional-grade sounds required expensive physical hardware. A vintage Moog synthesizer, a Neve console, a Lexicon reverb unit — each one cost thousands of dollars and took up rack space. VSTs put those same sounds into software at a fraction of the cost, which is a large part of why independent music production exploded in the 2000s. Today a single producer with a laptop has access to sounds that would have filled an entire studio floor twenty years ago.

Think of your DAW as the kitchen, and VSTs as the ingredients and equipment — the better your toolkit, the more you can cook.
