What's the difference between Personal and Studio?

Personal ($39) is for one person — unlimited use on one active device at a time. Activate on a new device and the old one signs out. Studio ($199) is for teams and commercial client work — unlimited team members, early access to new tools, and a commercial license.

Do I need an account?

No. Use any tool free up to 5 times per day on compute-heavier tools, and unlimited on lightweight ones. No card, no account, no signup required.

Where are my files processed?

Right on your device. Files never upload to any server. Everything runs in your browser — you can verify in DevTools → Network.

What happens if I use my Personal license on a second device?

The new device activates and the old device signs out. Your license key stays the same — you just move it between devices as needed. No limit on how often you switch.

Does this work on my phone?

Yes. Every tool works on iPhone, Android, tablet, and desktop.

What if I want a refund?

30-day money-back guarantee on both tiers. No questions asked. Email sales@cipherforces.com.

Will you add more tools?

Yes. New tools ship regularly. Your license includes every tool we ever release — Studio members get early access.

About Merge Audio Files.

Merge Multiple Audio Files Into One — In Your Browser

Drop in your clips, drag them into the order you want, and CipherForces stitches them into a single audio file. Turn on the optional crossfade and each track blends smoothly into the next instead of cutting hard. It reads MP3, M4A, AAC, WAV, OGG, and FLAC, resamples everything to a common rate, and exports one clean 16-bit WAV.

The whole thing runs locally with the Web Audio API — your files are decoded, joined, and encoded on your own device. Nothing is uploaded, there is no account, and there is no watermark or forced length cap beyond what your browser's memory allows.

One honest tradeoff: the output is lossless WAV, which is large — roughly 10 MB per minute of stereo. That keeps the quality perfect for further editing, but if you need a small file to share, run the merged result through an MP3 converter afterward.

Podcast assembly: Join an intro, the main recording, and an outro into one finished episode.
Voice memos: Combine several dictated clips into a single continuous recording.
DJ-style sets: Chain songs together with a crossfade so there's no gap between tracks.
Audiobook chapters: Merge chapter recordings into one file for easier listening.
Lecture and lesson notes: Stitch recorded segments back into the right order after editing.
Sound design: Lay loops and effects end-to-end to build a longer bed.

Privacy: This tool runs entirely in your browser. Your audio files are decoded, merged, and encoded on your device using the Web Audio API and are never uploaded to any server.
