SFX Synthesizer

This is not an app to play music with a virtual keyboard but a synthesizer to create sound effects. All elements of a sound: volume, frequency, low-pass and hi-pass filters cutoff frequencies can be modulated in time by creating envelopes with an intuitive drag and drop interface.
The app starts with the "time" view. There you can adjust the "time points", i.e the points in time where some change will happen to your sound. In the other screen you set up
- point by point
- the volume, frequency and filter characteristics of your sound. Choose one of the 8 available base waveform, click on "play" and listen to the sound effect you've created!

If you find it hard to generate interesting effects, you can find inspiration from a full range of 15 presets. The sounds you create can then be saved in wav format and used everywhere in your smartphone.

Works great for the most part and the features are solid. Just needs some layering to go along with it. Instead of just the 2 filters, maybe 2 slots for other filter types as well like comb or vocal types. Maybe a waveshaper. Look into making a granular synth generator. It'd be amazing if this had the power of the VSTi program Absynth because it is really good with envelopes and this could be that amazing and I would definitely pay for those features.

I needed an app to make frequency and volume slides. Small and effective app 👌👍.

Idk much about making SFX yet, but I can tell that this is the only FREE app I know that actually let's you make your own unique SFX. Most SFX apps I've seen only gives you a library of ready made SFX. This app gives you a lot of control and freedom by just using some of the basic components of producing sound. Though, I would still want more features to improve the workflow of making sounds. Like being able to zoom in and out when you have a lot of nodes. Also, add ways to set exact node positions, add more fundamental components of producing any sound (if there's more), and being able to know the exact value of the volume and filters. Also, increase the maximum duration of the sound playback, if possible.10,000 ms isn't enough for me. Looking forward for updates.

This is the Loudest and Sharpest sound creation tool for Android©. The controls are very basic but it's all you need.If you want to create a ringtone that is 'distinctive', or just want something that will make people say~ "what'n heck's that sound?" This is the app to use! Well Done Mr Developer!!!
