Sino

Sino is a simple test tone generator. Use it to test your speakers, headphones, studio monitors or PA system. In portrait mode, use one big dial to slide through the whole audible frequency spectrum single-handedly. In landscape mode, two sliders for frequency and amplitude control make it easy to swipe with more precision. Choose between a sine oscillator and band filtered pink noise. Send the signal to the left, right or both channels of your stereo setup. With its precise frequency slider, you can find problematic frequencies in your room easily.
