Slowed Reverb WAV
For creators who need the best audio quality: export your slowed reverb tracks as uncompressed, lossless WAV files. No compression artifacts, no watermarks, no compromises.

WAV is the format of choice when audio quality is non-negotiable. Unlike MP3, which uses perceptual encoding to discard audio data that most people cannot hear, WAV stores every sample exactly as it was rendered — a bit-for-bit perfect copy of the audio coming out of the processing graph. For DJs playing on club systems, producers who need to re-import tracks into a DAW, and archivists who want a lossless master, WAV export is essential. It is a Pro feature because the file sizes are significantly larger (a 4-minute WAV at 16-bit/44.1kHz is about 40MB versus 4MB for 128kbps MP3), and the bandwidth costs are real.
Our WAV encoder is hand-written in TypeScript — no external library, no dependency to audit or update. It produces standard 16-bit PCM WAV files at the sample rate of your source audio (typically 44.1kHz for music). The implementation is about 40 lines: write a 44-byte RIFF header with the format chunk and data chunk, then interleave the left and right channel samples as 16-bit signed integers (little-endian). The result is a WAV file that opens in every DAW, audio editor, and media player on the planet — guaranteed, because the format has been unchanged since 1991.
Why WAV over 320kbps MP3? For most use cases, 320kbps MP3 is audibly transparent — in blind ABX tests, even trained listeners struggle to distinguish 320kbps LAME MP3 from the original WAV. But WAV has two advantages that go beyond perceived quality. First, it is lossless: you can re-encode to any other format later without compounding generation loss. Second, some workflows require WAV specifically — burning a CD, submitting to a music distributor, or loading into older DJ hardware that does not read MP3 reliably. If either of those applies to you, WAV is the right choice.
Pro users also get WAV exports without the watermark and without the 3-minute duration cap — you can export a full album-length slowed reverb mix as a single lossless file if you want. And because the export uses OfflineAudioContext, the render time is the same regardless of output format: the audio graph runs once, then the encoder writes either MP3 or WAV. Choosing WAV does not slow down your export; it just produces a larger, lossless file.
If you are on the fence about Pro, consider how often you export. If you make one slowed reverb edit a month and only ever share it on social media, the free 128kbps MP3 is all you need. If you are a content creator posting weekly, a DJ building a slowed reverb set, or a producer who treats slowed reverb as part of your sound design toolkit, the Pro tier pays for itself the first time you export a WAV master that you can archive, re-edit, and re-encode for years without quality loss.
Frequently asked questions
- What is the difference between WAV and MP3?
- WAV is uncompressed and lossless — every audio sample is stored exactly as rendered. MP3 is compressed and lossy — some audio data is discarded to reduce file size. A 4-minute WAV at 16-bit/44.1kHz is about 40MB. The same track as 128kbps MP3 is about 4MB, and as 320kbps MP3 is about 9MB. WAV is ideal for archival, professional editing, and scenarios where you need to re-encode later without quality loss.
- Do I really need WAV or is 320kbps MP3 enough?
- For most listeners and playback scenarios, 320kbps MP3 is audibly transparent. Choose WAV if you plan to re-import the file into a DAW for further editing, burn it to CD, submit it to a distributor, or archive it as a lossless master from which you can encode to any future format without accumulated generation loss.
- How is the WAV file encoded without a library?
- The WAV format is elegantly simple: a 44-byte header (RIFF descriptor + format chunk + data chunk) followed by raw PCM sample data interleaved as 16-bit signed integers. Our implementation is about 40 lines of TypeScript — small enough to audit, zero dependencies to maintain, and produces standard WAV files compatible with every audio tool since Windows 3.1.
- Why is WAV export a Pro feature?
- WAV files are 8–10× larger than MP3 exports. Hosting and bandwidth costs for lossless downloads are correspondingly higher. The Pro subscription ($6/month) covers those infrastructure costs while giving you unlimited WAV exports, no watermarks, and no duration cap — a fair trade for users who need professional-grade output.
