GOOD AP, BUT...

....Many Apple songs have a DMT lock so you cannot equalize them. It is not the apps fault, it's some legal copy right issue. So out of my entire song library of 500songs I can only tweak like 20. Sorry if I missed it but, I wish it would just say that right on the first page. I don't have the knowledge or resources necessary to unlock the DMT. VERY FUN and EASY TO USE THOUGH. My earbuds are $7 so I wasn't expecting a miracle. I'm after earth shattering bass bustin out of my buds while I walk down the street....met but didn't exceed my expectations, with better quality buds you'd probably be golden and not need anything.

Response from developer

Nous sommes désolés d'apprendre votre mésaventure. L'application fonctionne avec les morceaux stockés directement sur votre appareil ou les titres que vous avez achetés et qui ne sont pas protégés par DRM. Pour utiliser l'égaliseur, assurez-vous que l'application est autorisée à accéder à vos fichiers multimédias et à Apple Music. Ensuite, lancez la lecture d'un morceau depuis votre bibliothèque, appuyez sur le titre en cours de lecture, et les options « Amplification des basses » et « Égaliseur » apparaîtront au centre de l'écran. Vous pouvez également consulter la FAQ dans l'application pour obtenir un guide pas à pas. Si vous avez besoin d'aide supplémentaire, veuillez nous contacter à l'adresse support@twinbit.net ou via les sections « Contacter l'assistance » ou « Signaler un problème » dans les paramètres de l'application. Nous sommes toujours ravis de vous aider.

FAQ

What does the Equalizer Fx app do?

This app enhances your music listening experience by providing a powerful 7-band equalizer and bass booster. It allows you to modify sound effects using pre-set amplifiers or by creating your own custom presets. You can also enjoy background music playback and stream radio stations.

What are the key features of Equalizer Fx?

Key features include powerful bass-boosting effects, a 7-band EQ with DJ transitions, elegant music visualizers, the ability to create custom equalizer presets, background music playback, and radio streaming. It also offers a variety of pre-set equalizer options like Acoustic, Bass Booster, Classical, Hip Hop, and Rock.

How much does Equalizer Fx cost?

The app is free to download, but requires an auto-renewing subscription for full functionality. Subscriptions are available on a monthly or yearly basis. A free trial period is offered, which automatically renews to a paid subscription unless canceled at least 24 hours before the end of the trial.

What devices is Equalizer Fx compatible with?

The app is designed for iPhone and iPad devices. It requires unencrypted raw audio data to apply effects, meaning it cannot apply equalizer, bass boost, or volume boost to DRM-protected music such as Apple Music tracks unless the songs have been purchased and owned from iTunes.

Can I use this app with Apple Music?

You cannot apply equalizer, bass boost, or volume boost to DRM-protected music, which includes Apple Music tracks. The app needs unencrypted raw audio data to function. However, if you have purchased and own songs from iTunes, you can use the app with those tracks.
