Start off on the right note every time with Onyx. This beautiful pitch pipe sports a three-octave range in C-C or F-F, with your choice of carefully crafted sounds: choose piano or clarinet to hear your note for several seconds, or switch to continuous playback mode* to loop strings or horns for as long as you like. Or, for pinpoint accuracy, use our custom sine wave generator instead and avoid those annoying loud pops that other apps can create.
