viert / go-lame Goto Github PK

Hi there! This seems like a super useful library for a project I'm working on that needs to do a bit of wav > mp3 transcoding, but I'm not really sure how to actually use the library?

Even just running go get "github.com/viert/go-lame" fails, since it can't find lame/lame.h. I'm not familiar with calling code via cgo, so if any additional setup instruction could be provided, it'd be super helpful.

Cheers!

When reading a wav file (generated by github.com/go-audio/wav) there is an audible click at the start of the resulting mp3 file.

I wonder, is it treating the wav file header like audio data? I don't know enough about wav files and lame to have an intuition as to what is causing this.

When I use the code exactly as per the readme it works out of the box except for one important problem.

When used on mac os x, on a sample wav file, the mp3 plays faster than the wav file. The mp3 audio and sounds like a sped up chipmunk.

The bitrate of the input file is 22khz / mono / 16bit. It appears that the library doesn't read the metadata of the wav file. So it assume your code must first open the wav file, read the metadata, then pass that metadata on to go-lame. It would be more convenient if the library just used the metadata inside the wav file. cf github.com/go-audio/wav

What encoding should be used in the ID3 strings?

Hello @viert! I have the same ask for this package as for the previous one :)

Also, new pkg.go.dev website doesn't show documentation for non-licensed projects.

Hi!

I have created a package to decode from another type of file to mp3 using lame-go.

https://github.com/Wameuh/Golang-AudioConverterToMp3

My issue is when I try to set the VBR mode to default lame.VBRDefault, the output file is not correct (wrong duration for instance).

To be more accurate, when I try to open the file with an mp3 player (like VLC), the duration is not correct.
