Add static noise between stations #4

...Ohhh... You working on this project again? Cool! I got as far as buying an 18's Sharpe radio cassette and some retro GTA stickers. Going to do a ViceCity version eventually!

@chunkysteveo Yes I've been fixing bugs lately (check out the commits) and been thinking on how to implement the noise :) I'd like it to be dynamic, so we can hear other stations mixed with synthesized noise.

chunkysteveo commented 5 years ago

That would be cool, some randomly generated white noise pattern or similar.

raphaelyancey commented 5 years ago

I implemented a static noise feature in the ftr_noise branch. Works by increasing noise tracks volume when any station volume is below a threshold. Will merge into master when I'll get the chance to test it on a Pi very soon.

Noise tracks are not included, but I recorded some on my synthesizer you can use! They must be placed in the NOISE_PATH.

I only hear the noise when I'm at the end of my virtual band (not between my stations)

raphaelyancey commented 5 years ago

@SebDominguez That's most likely because the script thinks the noise files are regular stations.

I think this is due to a bad installation on my part. When I run the install script, it was stuck on the scipy install for more than 1 hour. I tried to install scipy after expanding my swap but still it seems that this. package won't compile on my Pi (or is just taking forever)

It is taking forever, because scipy is a very big package and doesn't come precompiled for ARM as far as I know. On a Pi 3B+ it can take between half an hour and an hour.

The funny side is that the script is using only one fonction from scipy so it definitely can be optimized by rewriting this function and getting rid of scipy.

If you still experience the issue, please double-check that you are on ftr_noise. If not you should execute cd /home/app && git checkout ftr_noise & reboot or relaunch the script manually. That's because the default installation will install from master and this branch doesn't handle noise files yet.
