Many people have asked me to recommend which app from all of the apps we have built they should use and what would be the best frequency for them.
In this post I will do my best to explain how I would approach our different music retuning tools, from the point of view of someone who has just stumbled upon the concept of re-tuning music for the very first time and curious what it can do for them.
The following path tracks the exact journey I took as I developed each and every new solution, so I genuinely recommend you go through each step if you want to be able to make an educated decision if the power of re-tuning music is impactful and significant for you as it was for me and my family members.
Step 1 (free): An introduction to sound frequencies through a simple “Find your frequency” test.

The first time I officially heard about sound healing frequencies and how they could improve our wellbeing was during COVID. I don’t remember if it was on Joe Rogan’s podcast or some other free thinking podcast but they mentioned the ability to use sound frequencies to combat different medical issues and that immediately caught my interest.
After living for many years in high stress environments such as Los Angeles and various cities in Israel, then moving to a suburb of Boulder in Colorado, it made perfect sense to me. I saw first hand how moving from such a busy soundscape to such a quiet soundscape made enormous impact on our wellbeing, that hearing about the fact that sound, or the lack thereof can have a monumental impact on our wellbeing just made sense.
I started digging deeper into the subject, particularly around how it can help mitigate COVID symptoms and help combat it and became obsessed with learning as much as I can on the topic.
But then we actually got COVID, and when one of our family members was battling post covid insomnia, we decided to put these frequencies to the test.
Not knowing which of them would be the right one for the job, we reached out to one of the leading sound healing therapists in the world for help.
During the session with them they conducted a simple sound test where they played different frequencies and asked the family member to simply tell them which sounded and felt the best.
Once selected the sound healer provided her with a 30 minute meditative music recording that was pre-tuned to that frequency and prescribed it as one of the ways that would help them sleep. This entire call with this person took 8 minutes, was only done once and cost $150!
Our family member used the music provided and it did work, for a short while.
Soon thereafter, their frequency changed and they needed to redo the test, but we didn’t want to pay $150 again for such a simple test.
So I came up with our own version of the test and decided we should provide it free of charge, so anyone could take it as many times as they want, whenever they felt like they needed to, without having to book a session and wait on someone’s availability.

I believe that because we are dynamic, ever evolving people, self diagnosing ourselves at one point would provide you with totally different results than when you retake it down the line.
This means that being able to self test ourselves to find our own frequency is a crucial step that helps us land on the right frequency that is right for us for the particular situation or moment in time we are in. I encourage you to take it whenever you feel the need for it.
Step 2 (free): Re-tune your favorite song and see how it feels.
So finding what frequency sounds the best for you is nice, but now let’s see how it affects your favorite song!
But, before you dive into the process of re-tuning your entire catalog of music, I recommend to simply pick your favorite song and head to SongRetuner.com – on this website you will be able to upload your music file, select the desired output frequency, click “Retune Now” and within a few seconds download the re-tuned version of that track.

Next you will be able to play both versions of your track – the original recording and the re-tuned version and compare between them to determine which frequency tuning sounds the better to you.
SongRetuner.com is free to use, and aside from a single banner promoting one of our apps, is intentionally left ad free.
As I was going through the process of re-tuning one song to 10 different frequencies I quickly realized just how time consuming the process is and how much clutter it created in my music library. After all, having to store and manage 10 versions of the same song seemed a bit crazy, especially when I already have over 100 GB of music on my computer from the days I used to DJ. The app discussed in the next step solves both of these problems.
Step 3 (free trial): Re-tune your entire music catalog using HZP

HZP is our flagship music app that enables you to enjoy listening to your entire music catalog + over 1 million songs provided by Audius, re-tuned to any of the solfeggio frequencies and 432 Hz with one click.
You can choose the output frequency of the music before or while you are playing the music, making it possible to hear the re-tuning happening in real time. For the first time ever, we are now able to quickly hear any song being played at 10 different frequency tunings simply by clicking on a simple menu.
Unlike the previous step, you do not have to wait for the song to be converted, nor do you have to manage duplicate copies of each song. You can simply select the desired output frequency and enjoy the music.
As you finish listening to the first song and move onto the next, try to play the re-tuning frequency feature again, and see if the previous frequency still sounds the best. Oftentimes a certain frequency tuning would be great for one song, but awful for another. The power to control the frequency tuning of every song you listen to is now 100% in your hands!
You are now free from having to find music that was pre-recorded in a certain frequency tuning, or dependent on sound engineers or a website like ours to convert files for you.
HZP will make sure your music is always in the right tuning frequency for you!
You can try HZP for free, and once the trial is over a paid subscription will unlock unlimited music re-tuning so you can enjoy it all the time. Visit https://hzp.co
to get started.
HZP is available on all platforms including: Web, Windows, Mac, iOS, Android, Android TV, Amazon TV, Android Auto & Apple CarPlay. It works with any Bluetooth device and supports playback in background mode on mobile and you can control the music from the lock screen too!
Further, your paid subscription to HZP will sync your settings (but not yet your music unfortunately) between all of the devices, allowing you to enjoy the app on all of the different devices you own.
Lastly, if you subscribe to our Amplify subscription tier through your mobile device, you will be able to share your premium subscription with everyone in your family’s account!
Step 4 (Paid): Retune only your local library with Solfeggio Frequencies Player & Player Plus series of apps.

If you have used HZP and concluded that you indeed enjoy the ability to re-tune your music but:
- Only want to re-tune music stored on your device
- Don’t want to pay a subscription
- Are worried about your privacy
Then our next series of apps were built exactly for you!
SFP (Solfeggio Frequencies Player) – this music player application is a simplified version of HZP that will re-tune music stored on your device to any of the solfeggio frequencies and 432 hz tuning in real time.
How SFP differs from HZP:
- It does not require to sign up and create any account, thus no tracking or optimizations are done on our side
- It does not include the SYQEL music visualizer
- It is sold as a one time purchase per platform and does not require a subscription, nor can the license be shared with family members
- It is only offered on Windows, Mac, iOS and Android.
- The mobile versions will also work with Bluetooth devices, Android Auto & Apple CarPlay
SFP is a great solution for those who are looking only to re-tune music they already own and have stored on their devices.

However, because a good amount of people are only interested in re-tuning their music to a specific frequency such as 432 Hz, 528 Hz or 963 Hz, we created the Player Plus series of apps.
Player Plus apps are identical to SFP, but are limited in the frequencies they re-tune the music to by default, thus are offered to you at a lower price!
For example, 432 Player Plus will re-tune all of your music by default to 432 Hz, but requires an in-app purchase to unlock additional frequencies. By making the apps work this way, we have made it possible for people to purchase exactly what they want, have more control on how their money is invested to ensure you are getting the for your invested time and money.
People who purchase any of the Player Plus apps can unlock all of the frequencies with an in-app purchase within the applications, making them essentially comparable to SFP.
Unlike HZP, SFP and Player Plus apps are sold separately, per platform and cannot be shared with family members.

Step 5 (free trial): Re-tune any song on YouTube, YouTube music or Apple Music with MusicRetuner.com
One of the biggest complaints we get from people is “I don’t own any music and Audius doesn’t have my favorite artist…”
We heard them loud and clear and worked around the clock to find a solution that unlocks the largest music catalogs available to people – Apple Music & YouTube Music.
Both of these companies offer a giant catalog of over 100 million songs each, similar to other popular service providers such as Spotify, Tidal, Deezer, Pandora and Amazon music.

Our browser extensions offer people like you the ability to re-tune any song on YouTube, YouTube Music or Apple Music, in real time, exactly in the same way that you would on HZP.
The Music Re-Tuner browser extensions can be installed on Chrome, Edge, Firefox and Brave browsers and used on any desktop or laptop computer that has either of those browsers.
In some android devices, you are able to install the Firefox for mobile browser and use the browser extension on your mobile too.
We offer a 7 day free trial on the monthly and annual subscription for the browser extension.
A one time payment option is also available for those who want to use the extension without having to worry about another subscription showing up on your credit card statement regularly.
Option 6 (Free): Re-tune your music instrument to the frequency tuning you love most.

For the musicians in the audience, who are interested to re-tune their music instruments, we created Solfeggio Frequencies Tuner – a free online resource that provides them with a dynamic scale table that gives them the accurate frequency each note would need to be tuned, when anchored around each of the different Solfeggio frequencies and 432 Hz.

We hope you experience the music you already listen to in an amazing new way.
Love, peace and harmony to all,
Yoav
