*Augmented octave and diminished unison on C = C♯. Equal-tempered: 21/12:1 = 100 cents. MIDI pitch bend: none Note how the diminished unison is essentially equivalent to the augmented unison.
A sound file playing the interval of an augmented fifth, in equal temperment. The first tone is a sine wave at 300 Hz, the second is at 476.1 Hz, the last is the interval. Made with NCH Tone generator.
A field recording of small waves crashing on a sandy shore. Part of the recording includes the waves splashing against a wooden structure. The waves come a fast, regular intervals; this isn't the slow rolling crash of a barrel wave on the beach. There was a bit of wind (generating the waves) which i've did my best to minimize, but if you don't want wind in the recording you're going to need to edit around it. Always curious to see where these recordings wind up, so if you use it drop me a link in the comments if you think about it.
