Swaran Solfeggio X

Swaran Solfeggio X: Verified Solfeggio and 432Hz Frequency Conversion

Zero tolerance for sloppy Hz math.

Swaran Solfeggio X is a Windows workstation built around one refusal: it will not hand you a retuned file it has not personally checked. Feed it a WAV, MP3, or FLAC file. Every conversion runs through Śruti Lock, is visible the entire time in the Control Room, and ships with its own Hz Receipt, proof of exactly what happened, not a promise that it probably worked. Feed it any of the nine Solfeggio frequencies, 432Hz, 440Hz, or a target you choose yourself, and what comes back is mastered, 24-bit, at your file’s own sample rate, with nothing about the pitch left to guesswork. This is not a converter with extra features bolted on. It is a small, exacting piece of engineering built by someone who spends real working hours inside a DAW and got tired of tools that simply ask to be trusted.

You watch the whole thing happen. The Control Room narrates every phase in real language, not a spinner: loading the waveform, the first shift, the correction pass, the final check, each one its own honest line rather than a progress bar standing in for the truth. One of them reads, verbatim, “Verifying expected vs analyzed Hz with no mercy for rounding errors.” It means it. When it is done, play the result back without leaving the app.

What it does

• Accept WAV, FLAC, or MP3 as a source, so you are never stuck converting a file first just to feed it in.
• Convert to any of the nine Solfeggio frequencies, 432Hz, 440Hz, or a custom target from 20Hz to 20,000Hz, each one locked in by Śruti Lock before the file is considered finished.
• Start from your file’s real pitch, not an assumption. Śruti Lock measures what your source actually is before calculating anything, since very few real recordings sit at a textbook-perfect 440Hz.
• Keep working when the easy method does not land cleanly. On material that resists a confident first reading, Śruti Lock automatically switches to a different detection approach rather than shipping a shrug, and says which one it used on your Hz Receipt.
• Watch every phase live in the Control Room, in plain language, as it happens, then play the finished file back inside the app itself.
• Get a real Hz Receipt with every single conversion: the exact target, the exact measured result, the exact margin, and a pass or fail you can check yourself. A real one reads exactly like this: target 417.00Hz, measured 415.30Hz, delta 1.70Hz, PASS.
• Run the same file through Swaran Solfeggio X twice, a year apart if you like, and Śruti Lock hands you the same measured result both times, checked before anything ships, not hoped for afterward.
• Keep your track exactly as long as it was. A retuned file plays for precisely the same duration as the source, so it drops into a set or a session without a second of re-syncing.
• Shape the result with four mastering characters built for real material, Crisp for rock and percussion, Smooth for ambient and drone, Warm for acoustic and jazz, Neutral for transparent cleanup, each one previewed live the moment you hover it, or take full manual control of every EQ band and transient parameter yourself.
• Mastering that cannot undo what Śruti Lock already proved. The enhancement pass runs after the pitch is measured and locked, never before, exactly as the app itself discloses on screen while it works.
• Get the honest margin, not a flattering one. The pass threshold widens slightly for low frequencies, since measuring pitch down there is a genuinely harder problem, and Śruti Lock says so on the Hz Receipt instead of quietly hiding it.

Who this is actually for

• Musicians and producers releasing a retuned track. A retune that is approximately right is audible against everything else mastered at standard pitch. Convert, let Śruti Lock verify the result, check the Hz Receipt before it ships.
• Sound and meditation practitioners working with the Solfeggio set. A session built around a specific frequency needs the real, verified audio, not a description of a number. Select the target, convert, keep the Hz Receipt as your own record of what the material actually is.
• DJs and live performers matching a track to a set. A mismatch is audible next to everything else in the set. Convert ahead of the performance, verify with the Hz Receipt, shape it with a mastering template so it is set-ready, not just pitch-correct.
• Audio engineers matching an unusual reference pitch. Not everything is tuned to 440Hz, an orchestra, a vintage recording, a sample library at its own tuning. Enter the exact target in the custom frequency field, and Śruti Lock measures what your source actually is before calculating anything.
• Sample library and virtual instrument developers. A sample pack only works if every file is actually at the tuning it claims, and checking hundreds of samples by ear is not realistic. Batch convert the whole set in one run and get an independent, written Hz Receipt for every single file.
• Broadcast and post-production engineers. Conforming a score or a dialogue pass to a project’s reference pitch cannot touch the tempo, since drifting out of sync with picture is not acceptable. Duration preservation is built into every conversion, not an afterthought.
• Archivists and restoration engineers. A large share of historical film and television audio was permanently pitched up by exactly 4% during PAL broadcast conversion, and every existing fix calculates a correction and trusts it. Enter the precise correction target, let Śruti Lock verify the restored pitch, and keep the Hz Receipt as part of the restoration’s own record.

Frequently asked questions:

What operating systems does Swaran Solfeggio X run on?

Windows 10 and Windows 11, 64-bit.

How much does it cost, and is it a subscription?

₹5,999, once. No subscription. One license covers two devices.

What formats can I export to?

24-bit WAV or FLAC, one or both, at your source file’s own sample rate.

How is this different from other Solfeggio or 432Hz conversion tools?

Most of the other tools calculate a shift and stop. Swaran Solfeggio X measures what actually came out the other side, through Śruti Lock, and hands you an Hz Receipt proving it. If the first pass misses, it tries again automatically. The tool preserves the exact duration of your original audio as well. It also provides Masting Elements that helps you finish the final audio without leaving the workstation and this mastering suite is designed in such a way that it does not affect the final audio tuning in any way.

Is there a trial or a refund policy?

No trial and no refund. Swaran Solfeggio X is sold as a digital download, and the purchase is final once your license key is issued.

Can I convert to more than one frequency from a single file?

Yes. Select as many targets as you want, and Śruti Lock verifies each one on its own, with its own Hz Receipt.
