PitchBox

PitchBox is a lightweight and very practical Java-based piece of software that makes it as simple as possible for you to transform your voice or any audio recording via a set of funny and appealing sound effects.

The provided effects are as follows: Echo, Flanger, Pitch Shift, Whisperize, Robotize, Graphic Eq., Detune, Ghost Dance, Mizerablize, Beat Filter, Thor, Distort, Water, STN Equalizer, Octaver, Zombify, Vocoder, and Pitch Screw.

Apart from making sure that Java is present on your computer's system, you'll also want to make sure that your computer has an ASIO-compliant sound card in order to ensure the best, low-latency results.

Other than that, you should be able to run PitchBox right out of the box, without any type of configuration.

Simply launch the app, select the audio source from either Audio In (microphone) or from a music file (the app supports almost all major audio formats), choose the desired audio effect, tweak its intensity from the slider on the lower part of the main window, and that's about that.

Of course, you're provided with other, more advanced controls, easily accessible within the Settings section. For instance, you can also choose the sample rate, buffer size, and choose the audio channel mode, just to give you an example. The app also allows you to select specific devices for the both the recording and the playback process.

Taking everything into account, PitchBox is a useful and very efficient application that delivers quick voice changes with the help of its nifty collection of effects. As mentioned before, a soundcard with native ASIO support is recommended if you're aiming for the lowest possible latency.
