Build a simple binary out of this that takes an mp3 or wav file as parameter and returns the key about libkeyfinder

[ritschwumm]

+1, exactly what i'm looking for right now. i thought i might write one, but right now i can't figure out how to even build the lib on ubuntu :(

[aybe]

I've just tested the following procedure and it built the library under Linux Mint 17:

• download and install Qt Online Installer for Linux : http://www.qt.io/download-open-source/
• from Software Manager install : libboost-system1.55dev, libboost-thread1.55dev, libfftw3-dev
• open Qt project, run Qmake and build project

Now for the CLI application itself you can probably find some inspiration from the Windows version I've made out of the library :

Functions I needed to 'export' from the library:
https://github.com/aybe/libKeyFinder/blob/master/c_api.cpp

Skeleton of how to call the library:
https://github.com/aybe/LibKeyFinderDotNet.BASS/blob/master/LibKeyFinderDotNet.BASS/KeyFinderBass.cs

Basically, my fork of the library changes nothing to the original lib., it only adds c_api. and c_api.h.

Note that I use BASS library for reading PCM from any file type, it is also available for Linux : http://www.un4seen.com/

Unfortunately I can't help you out regarding Linux development since I lack programming knowledge under this platform. A rough guess though would be to create a new QT console application and reference the original project, then re-implement the skeleton above.

Note: you will find all relevant info. + code about my version at https://github.com/aybe/libKeyFinder

Good luck :D

Hi again 💃

I've just wrote a quick and dirty CLI app for Linux, it's not as mature as my C# project but it does its job.

Obviously you'll need to setup the environment as I said on previous post first plus:

• create a folder
• checkout original library in it
• checkout the CLI app in it
• unzip the BASS SDK in it
• load the PRO file in Qt

Feel free to improve it and contribute back !

[ritschwumm]

great, thanks :)

[gobijan]

Superb Job! I will try it out today!

[aybe]

Sorry I mistakenly inserted a syntax error :

Replace QStrProcessinging by QString

:D

Hi,

Here is a built version of the CLI app. :

http://1drv.ms/1wUE7Wa

• it's a 64-bit executable
• libbass.so should go to /usr/local/lib (well not sure it's the usual place but for me it works)
• call keyfinder -s "song.wav"
• currently it supports WAV / MP3, looking to support FLAC later

Let me know if it works on your side !

[gobijan]

Wow you're fast :)

It works great with .WAV files but MP3s are not beeing processed (at least for me). Do you know how to make it analyse mp3s, too? I checked the libbass.so version you provided and it seems to be supporting mp3. strange... hmmm

[ritschwumm]

i'm baffled - i didn't even find time to give it a try, and you're already finished. will try the executable right now :)

[gobijan]

@ritschwumm do mp3s work for you?

[ritschwumm]

wav works like a charm (which is everything i need right now), but mp3 does not.
no console output, and the return code is 0.

[aybe]

I'll take a look tonight, not sure why since 0 means that it worked.

Regarding the quality of mp3 analysis I would be careful since with other APIs such as SonicApi the results are biased regardless the mp3 bitrate. I was dubious when told that but it went to be the truth, in case ask the author.

[aybe]

Hi !

New version : http://1drv.ms/1DHSJeu

• MP3 fixed
• FLAC support

Currently libbassflac.so (in zip) must be located next to the application unless I harness the lib mechanism in Linux.

And this is the release build, it is much faster !

Let me know how it works for you 💃

[gobijan]

Nice! Just tested it and it works superb :) great work man! Exactly what I needed!!

[trostli]

@aybe Is your CLI tool still available anywhere? Would love to check it out!

[aybe]

Sorry, I've removed the repos ...

I'm almost entirely finished with a JUCE-based app that wraps this lib (amongst some other things), so I can strip it and dump a cross-platform JUCE CLI tool specifically for keyfinder sometime this weekend if there's actual interest. It'll be a bit bloated size-wise since I don't really want to tediously strip a bunch of boilerplate code out of what I have now, but it won't effect running speed.

[trostli]

That sounds like it would be quite useful Dylan! thank you

All done: https://github.com/SonicZentropy/ZenTermKeyFind

Works the same way the old one apparently did. I put an already-built Windows binary under releases. You can build for OSX/Linux if needed, instructions in my Readme. The libKeyFinder code may not be current...I pulled it straight out of my app, which means it's the version that was current as of whenever I submitted my most recent bugfix pull req here!

It's super quick and dirty, but should work fine. Let me know if you have problems and I'll fix em!
