WaveSmith 1.1 on Windows — waveform editor, tabs, and transport.

What this Windows audio editor is for

Record, cut an MP3, convert WAV to MP3, extract a soundtrack, or import a YouTube link you have the right to use. The file stays on this PC.

Record audio

Voice recorder for Windows: microphone, system loopback, or both. Punch-in a sentence without rebuilding the file.

MP3 cutter

Trim an MP3 on the waveform. Cut, copy, paste, export only the selection — the edit everyone searches on day one.

Convert WAV to MP3

Audio converter with 58 named export targets. Keep a float master; write an MP3, M4A, or FLAC copy next to it.

Extract audio from video

Open an MP4, MKV, or MOV. The soundtrack becomes the waveform. Export WAV or video-to-MP3 without a second gadget.

Audio effects

EQ, compressor, fade, pitch, reverb — plus noise reduction and LUFS. Named passes, not a mystery “enhance” slider.

YouTube to MP3

Paste a link you have the right to use. The MP3 downloads on this PC, then opens in the audio editor so you can cut it.

How to edit audio in three steps

Screenshots from the Windows app. Record or open a file, cut on the waveform, convert or export.

1. Record or open

Open a WAV or MP3, record audio (mic or system loopback), or File → Import from YouTube. Drag-and-drop works. The file stays on this PC.

Record audio in WaveSmith — microphone or system loopback — Step 1: 1. Record or open

2. Cut and add effects

MP3 cutter: select on the waveform, then cut or add audio effects — Step 2: 2. Cut and add effects

3. Convert or export

Convert/Export to MP3, M4A, FLAC, or 58 named targets. Batch a folder. Save keeps a 32-bit float master so you can keep editing.

Convert/Export to MP3, WAV, or 58 named audio formats — Step 3: 3. Convert or export

What's in the menus

Each tool has its own page: what the menu does, then a short how-to. Download when you want the Windows app.

WIN

Win64 waveform workstation (native dialogs)

A real Win64 .exe. Native dialogs. The file never has to visit a tab.

REC

WASAPI record: mic, loopback, punch-in

Microphone or system loopback, live meter, punch-in with preroll.

CUT

Cut, copy, paste, and crossfade

Trim MP3 and WAV on the waveform. Cut, copy, paste, export selection — the day-one edit.

Convert audio formats

Fifty-eight named export targets. The editor file stays a float master.

Audio effects: EQ, compressor, fade, pitch

EQ, compressor, fade, pitch, reverb, plus noise reduction. Named audio effects — not a mystery Enhance slider.

VID

Open video files as a waveform (MP4, MKV, MOV)

Open MP4, MKV, MOV, WEBM… the soundtrack becomes the waveform.

Import from YouTube (local yt-dlp)

Paste a link you have the right to use. yt-dlp runs locally. The MP3 opens in the editor.

Noise reduction & repair

De-click, de-hum, de-clip, de-ess, gate, DC remove — then a repair studio pass.

WAV

Waveform editor

See the take. Grab the region. Zoom until the transient is obvious.

BAT

Batch audio converter

Point at many files. Pick one target. Do not load them into the editor one by one.

Podcast editor & LUFS

One chain: clean voice, de-ess, loudness match. −16 is a preset, not a myth.

Split audio by silence

Long interview in. Tabs or WAV files out. Threshold is yours.

Straight answers before you install

Is WaveSmith free?

Yes. The Windows installer is free. No trial clock, no watermark on the file you save.

Does my audio leave this computer?

Editing is local. Convert and YouTube import run tools inside your user folder. This website only serves pages and the installer.

Windows only?

WaveSmith 1.1 is a 64-bit Windows app (Windows 10 and 11). That is the product.

Is YouTube import legal?

Only import links you have the right to use. WaveSmith does not bypass paid access or give you someone else’s catalog. You are responsible for the URL you paste.

Do I need an account?

No. Install, open a file, save. Language and window size remember on this PC.

What is the difference versus a DAW?

A DAW arranges songs on a timeline. WaveSmith is a waveform workstation: one file (or a few tabs), surgical edits, convert, deliver. Faster when the job is the file.

Can WaveSmith record audio?

Yes. Tools → Record (Ctrl+Shift+R) captures the microphone, system loopback, or both. The take opens on the same waveform as any other file.

Does it include a YouTube to MP3 converter?

File → Import from YouTube. Paste a link you have the right to use. yt-dlp runs on this PC; we do not see the URL. Then trim and export like any MP3.

Does the audio editor include effects and an MP3 cutter?

Yes. Cut, copy, paste, and trim on the waveform. Effects holds EQ, compressor, fade, pitch, reverb. Process holds noise reduction and LUFS.

Install it. Open a file. Feel the difference.

Free Windows 64-bit installer. WaveSmith 1.1.0. Your audio does not go to our servers — we do not have a place to put it.
