Show HN: SoundViz – Your favorite sound as beautiful art

"Hello Hacker News friend! Thanks for stopping by. Once you're done checking out SoundViz, we'd love to get your feedback."

... leads to https://www.soundviz.com/ I was kind of expecting that it would bring me to this comment thread.

If I went through with the purchase I think I'd couple it with a "press a button and playback the original sound" setup, as that would be pretty easy to add to the rfid triggered music playback system I've got one of my R-Pi's rigged up for.

I just played around with a test file and was really impressed by the slider controls to allow modifications. Very neat stuff.

The only suggestion I could think of was perhaps an option for me to add my own colormap?

Small issue: I grabbed an .m4a, uploaded it, and the screen just sat there. Console errors and whatnot. Didn't take a rocket scientist to guess that .mp3 might work better (it did). So I'm all good, but just reporting it.

Again, really good stuff, congrats.

I'm curious to see whether there is a market for this, but I already spend so much of my time looking at waveforms I'm not sure I want to look at more. Have you considered spectrograms or spectral phase diagrams, both of which can be considerably more visually interesting than a straight waveform?

Agreed on messaging/processing indicator.

The size of the bars is based on the amplitude of the sound you're processing, so your results will vary, depending on the dynamics of the sound. Have you tried In Rainbows? ;)

Recording - You are correct. I think a count down would also be useful. Currently, the recording starts as soon as you hit the button, which can produce some silence at the beginning of the recording if you're not on it. I like the playback idea a lot, though.

Thanks again!

If not, if you sign up, I can create a draft for you so you can play around.
