Review: Voice Synth (iOS App)

I was excited to try Voice Synth because the concept is interesting, but unfortunately the app is practically unusable with modern iPhones. The app seems to rely on using wired headphones with a microphone, which older iPhones supported through the built-in headphone jack. However, most current iPhones no longer include a headphone jack, and the app doesn’t appear to be designed to work properly with wireless Bluetooth headphones or other modern audio devices.

Because of this limitation, many users simply won’t be able to use the app the way it was intended. Unless you have specific wired hardware or adapters that work with it, the core functionality becomes extremely difficult—or impossible—to access. For an app that relies so heavily on audio input and monitoring, not supporting common wireless audio options is a major drawback.

In its current state, the app feels outdated and not compatible with the way people actually use iPhones today. Updating the app to properly support Bluetooth headphones and modern audio routing would make a huge difference. I would also give it five stars.

Response from developer

Hi Charles, when using AirPods, please open the AUDIO MIDI panel and select your device’s built-in mic as audio input. That reduces much latency, and bring back the totally-out-of-this-world experience of not only hearing but also “owning” Voice Synth’s real-time transform of your voice. Lowest latency is obtained with a with wired (USB-C) headset. For more assistance you can contact us at contact@qneo.net. Thanks, Qneo

This is a toy at best!

There’s no provision to connect the app to whatever audio interface you’re using and use a higher quality mic…only a Bluetooth or iPad mic??? The same with midi….bluetooth only. Apparently this app is more for consumer tinkers

NO LA COMPREN

ACABO DE TIRAR MI DINERO.

no vale la pena pagar 12 dolares por una app tan deficiente.

es una estafa.

Une Merveille

Pour les percussions acoustiques, pour se concocter des presets incroyables et s'éclater les paumes sur n'importe quoi, c'est la meilleure de l'AppStore !
En plus...c'est une des très rares qui permettent de choisir son entrée Audio! Depuis cette bouse d'USBC qui coupe les micros de l'iPad quand on branche un casque, c'est l'une des seules à permettre de contourner le bug. (Uniquement en standalone, hélas.) alors oui, elle commence à dater, mais pour tous ceux qui ont les mains qui démangent en permanence, c'est vraiment l'outil ultime.
