Solfeggio Frequencies Player is a cross-platform music player from SYQEL INC. Its main selling point is the ability to retune a user’s existing local audio library in real time to 10 Solfeggio frequencies: 174, 285, 396, 417, 432, 528, 639, 741, 852, and 963 Hz. It is not a generative AI tool in the sense described on the page, and the copy does not disclose any large-model or machine-learning capabilities. Its core is a real-time pitch/frequency shifting engine, which the company says is protected by U.S. Patent US 11,836,330.
The product supports MP3, FLAC, WAV, and most common audio formats, and can point to local folders for batch playback and retuning. Retuning happens in real time during playback: the original files are not modified, and no files are uploaded. The official messaging emphasizes that there is no EQ, no compression, no psychoacoustic enhancement, and no re-encoding, positioning it as an “honest” and precise pitch-shifting tool. Other features include one-tap frequency switching, a return-to-440 Hz option for A/B comparison, playlists, a sleep timer, and offline listening.
The free trial includes 20 retunes and does not require a credit card. Full unlock costs a one-time payment of $119.99 and includes all 10 frequencies, but licensing is platform-specific; in other words, different platforms may require separate purchases. The company offers a 14-day money-back guarantee, though App Store purchases are subject to Apple or Google policies. The privacy claims are relatively clear: no ads, no tracking, no listening-data collection, and files remain local.
The main advantage is getting the full frequency set in a one-time purchase, which is more suitable for heavy users than buying individual single-frequency apps at $19.99 each. Local processing, offline use, and relatively complete coverage across iOS/Android/macOS/Windows are also positives. Downsides include the high price and the lack of support for directly processing encrypted streaming services such as Spotify or Apple Music. The page also does not mention a Chinese interface, Chinese-language support, an API, or third-party integrations. In addition, the page provides no scientific evidence for the healing effects of Solfeggio frequencies, and the terms state that the product is not intended to diagnose, treat, cure, or prevent any disease.
It is best suited to people who already have a local music library and regularly use Solfeggio frequencies for meditation, sleep, focus, or mind-body work. It may also suit practitioners who need to switch frequencies quickly during therapeutic sessions. For occasional experimentation, the $119.99 entry cost is relatively high. Access from mainland China is not stated in the source material, so it is considered unknown.
