What other ways are there for generating audio?

@Sp3000 writing the file manually
well and there are code-based synthesisers

Oh ... k... null bytes and all? (I don't think any audio file has been all printable ASCII when I opened in notepad)

it's not like you can't write binary files ;)

I'd have to either figure out how the file format works, or make a file then kolmogorov it :/
(Never done any audio processing myself)

I remember manually reading wav once
not writing anything though
but I think I'll allow libraries
@Sp3000 can we generate one or two example files?

Would be good if we had some, will see in a bit

Python's got a few audio libraries, it seems (the first bunch)

@Sp3000 I'm currently generating a noise-based file manually in GoldWave
I think I'll reduce the minimum time scales a bit

Hmm k

sorry for trying out before release XD.

@bitpwner wow that's short
could you upload the result somewhere?
 
Sp3000
Sp3000
... you can do that?!
(was still trying to figure out how wave worked)

soundcloud is still processing

Oh nice beeps

beautiful...

seems like saw wave is most byte efficient

I thought that surely the big number was shorter if converted to another base, but both 0x and int("",36) are too long :/
Looks like you need 20 digits or something to be more efficient to convert

Martin Büttner
okay, I've got my noise file ready
@bitpwner I've reduced the minimum segment length to 0.2 seconds

soundcloud is really taking its time...

the first upload must have been borked... soundcloud.com/martin-b-ttner-7/2015-morse-example-1
afaict the challenge is good to go

managed to shave 2 more bytes with 0.2 secs.
soundcloud is really taking too long... i guess dropbox can do in the meantime.

try the upload again, the second upload worked immediately for me

Q: Morse the New Year

Martin BüttnerThis is Weekly Challenge #1. Theme: Audio Processing Your task is to write a program, which outputs an audio file (in a format of your choice), which contains the Morse code for 2015, i.e. ..--- ----- .---- ..... You are free to choose any sort of sound for the segments, like a single-frequen...
