undefined IS_Ltables

[AlexanderOMara]

Hey,

I tried using this plugin after installing it via NPM, but ran into some odd issues with the src/layer3.js file having some seemingly random typos throw in.

After debugging it, I determined one of the issues was MP3FrameHeader.FLAGS.tables.I_STEREO which should actually be MP3FrameHeader.FLAGS.I_STEREO. It seems this issue was fixed in the prior commit though, just the version on NPM is outdated for some reason.

Once I fixed that problem though, I ran into another very strange looking line of code.

var lsf_scale = IS_Ltables.SF_TABLE[right_ch.scalefac_compress & 0x1];

There is no IS_Ltables variable, and I think it is supposed to be:

var lsf_scale = tables.SF_TABLE[right_ch.scalefac_compress & 0x1];

This typo has not been fixed yet.

Strangely, SF_TABLE appears to be a simple Float32Array, yet array members on lsf_scale are being accessed further down the code. Did you manage to find a solution to this @AlexanderOMara?

I think it's supposed to be this: https://github.com/fasterthanlime/jsmad/blob/master/src/layer3.js#L183
