Stop Installing Audio Apps for One-Off Tasks
You recorded a voice memo and it sounds like you're inside a tin can. Your podcast intro is five seconds too long. A client sent you a FLAC file but you need MP3. Your YouTube rip is a video but you only want the music.
Every one of those jobs takes thirty seconds to fix β but traditionally you'd spend twenty minutes installing an app, creating an account, and watching a tutorial for a tool you'll never open again.
FileCrank's audio toolkit runs entirely in your browser. No download, no signup, no subscription. Here is what it can do and who actually needs each tool.
Convert Any Audio Format β Including the Obscure Ones
Tool: Audio Converter
Supports MP3, WAV, FLAC, AAC, OGG, M4A, AIFF, OPUS, WMA, and AMR in both directions.
Who needs this: A musician gets stems delivered as AIFF from a producer, but their DAW only imports WAV. A podcast host receives a guest recording as an M4A iPhone voice memo and needs it as MP3 before editing. A developer is building an app and needs test audio in OGG format.
The converter handles all of those in a single upload. Pick input, pick output, download.
Extract Audio From Video (The "Convert Video to MP3" Search)
Tool: Video to Audio
Supports MP4, MOV, MKV, AVI, and WebM as input. Outputs MP3, WAV, or AAC.
Who needs this: This is one of the most searched audio tasks online β people want the audio track from a YouTube rip, a lecture recording, a webinar, or a video interview. Upload the video file, extract the audio, done. You get a clean audio file without needing a video editor.
Fix and Clean Up Audio
Remove Background Noise
Tool: Audio Noise Remover
AI-based processing removes background hiss, fan hum, HVAC noise, and room reverb.
Who needs this: Remote workers recording calls on a laptop with a built-in mic. Podcasters who record in untreated rooms. Teachers recording lessons at home with ambient noise. The tool doesn't require you to manually set a noise floor β it detects and removes it automatically.
Boost Volume or Normalize Levels
Tool: Audio Volume Booster
Boost levels or normalize with a peak limiter to avoid clipping.
Who needs this: You recorded a voice memo and it's barely audible. Or you're stitching together clips from different sources and one is much louder than the others. Normalize both files before merging and they'll sit at the same level.
Equalize the Sound
Tool: Audio Equalizer
A 10-band EQ for boosting or cutting specific frequency ranges.
Who needs this: A podcaster who wants to cut the boxy low-mids from a voice recording. A musician who needs to quickly tame harshness in a demo. Not a substitute for a full DAW, but for quick corrective work it gets the job done.
Add Reverb
Tool: Audio Reverb
Room, hall, plate, and spring reverb presets.
Who needs this: A voice actor adding space to a dry recording. A musician who wants to give a synth pad some depth before sending it to a collaborator. A content creator adding atmosphere to a sound effect.
Edit Structure and Timing
Trim Audio
Tool: Audio Trimmer
Cut audio with a visual waveform scrubber for precise start/end points.
Who needs this: Anyone who needs to remove silence at the start of a recording, cut a long file down to a specific length, or isolate one part of a track. The waveform view makes it easy to see exactly where to cut β you're not guessing by timestamp.
Merge Multiple Files
Tool: Audio Merger
Joins multiple audio files with optional crossfade between them.
Who needs this: A podcaster combining an intro jingle, interview recording, and outro into one file. A teacher assembling separate lesson segments. The crossfade option smooths the transitions so they don't sound like hard cuts.
Split One File Into Parts
Tool: Audio Splitter
Split by silence detection, equal parts, or custom time markers.
Who needs this: A musician who recorded a full album as one long file and needs individual tracks. A language learner who downloaded a long lesson and wants it split into five-minute chunks. The silence-detection mode is particularly useful β it finds natural breaks automatically.
Fade In and Fade Out
Tool: Audio Fade
Adds fade-in at the start, fade-out at the end, or both.
Who needs this: Anyone who has ever had audio that starts or ends abruptly. A DJ exporting a mix segment. A content creator whose background music clip needs to ease in rather than hit hard. It's a small polish step that makes a noticeable difference.
Reverse Audio
Tool: Audio Reverse
Plays the file backwards.
Who needs this: Sound designers creating reversed crash effects. Music producers making reverse reverb tails. It's a niche tool but when you need it, you really need it.
Change Speed and Pitch
Speed Changer
Tool: Audio Speed Changer
0.25Γ to 4Γ playback speed with pitch preservation.
Who needs this: A student who wants to slow down a fast lecture to 0.75Γ to catch every word. A musician learning a guitar solo who drops it to 0.5Γ to follow the fingering. A podcast listener who prefers 1.5Γ speed and wants to pre-process files for offline listening.
Pitch Changer
Tool: Audio Pitch Changer
Shift pitch by semitones, with speed kept constant.
Who needs this: A singer who wants to practice a song in a lower key. A producer who recorded a vocal at the wrong pitch. A content creator who wants to anonymize a voice by shifting it up a few semitones without the chipmunk speed effect.
Create Ringtones
Tool: Audio to Ringtone
Trim any song and export as M4R (iPhone) or OGG (Android).
Who needs this: Anyone who wants a custom ringtone without paying $1.29 on iTunes or using sketchy ringtone converter sites. Trim to the chorus, export in the right format for your phone, and side-load it. No third-party apps, no iTunes library management.
For Podcasters and Streamers
Stereo to Mono
Tool: Audio Stereo to Mono
Mixes both channels down to a single mono file.
Who needs this: Podcasters who recorded with a stereo mic or interface and only want mono output β mono files are smaller, play consistently on all speakers, and are standard for spoken-word content. This is a common final-step task before publishing to podcast hosts.
Channel Splitter
Tool: Audio Channel Splitter
Splits a stereo file into separate left and right channel files.
Who needs this: A podcaster who recorded a two-person interview with each person on a separate channel (a common dual-mic setup). Splitting lets you apply noise removal, EQ, or volume adjustments to each speaker independently before recombining.
Record Directly in the Browser
Tool: Audio Recorder
Captures microphone input directly in the browser, no plugin needed.
Who needs this: Someone who needs to capture a quick voice note without opening a DAW or audio app. A remote worker who needs to record a quick voice message to send as a file. Works on desktop and mobile.
For Musicians and Producers
BPM Detector
Tool: BPM Detector
Detects beats per minute from any audio file.
Who needs this: A DJ who wants to know the exact BPM of a track before mixing. A musician who wants to match the tempo of a backing track to their recording. Faster than counting manually or hunting through a music app.
Audio Mixer
Tool: Audio Mixer
A 4-track mixer with per-track EQ and reverb controls.
Who needs this: A musician who wants to quickly blend a vocal, guitar, bass, and percussion track into a rough mix without opening a full DAW. Not meant to replace professional mixing β but for demos, reference mixes, or quick previews, it works.
Waveform Generator
Tool: Audio Waveform Generator
Exports a PNG or SVG waveform image from any audio file.
Who needs this: A podcast producer who needs a waveform image for a website thumbnail or social card. A musician who wants a waveform visual for album art. A developer who needs a static waveform image as a UI element.
Edit Metadata
Tool: Audio Metadata Editor
Edit ID3 tags: title, artist, album, track number, genre, artwork for MP3, FLAC, and M4A.
Who needs this: A musician who self-releases music and wants files to display correctly in media players and streaming services. A podcaster whose episode files are missing titles and show up as "Unknown" in podcast apps. Getting metadata right matters for discoverability on platforms that index it.
Why Browser-Based Beats Installing Software
Every tool on this page runs in your browser. That means:
- No installation. No 200 MB download, no admin rights required, no system tray icon you forget to remove.
- Works on any device. Laptop, Chromebook, tablet β if it has a browser, it works.
- Files are temporary. FileCrank deletes all uploaded files within one hour. There's no account, no storage, no risk of your audio sitting on someone's server indefinitely.
- No learning curve. Each tool does one thing well. You don't need to learn a full application to trim a ten-second clip.
For quick, one-off audio tasks, this approach is faster than any installed software.
