MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder
Last post by maikmerten -
Thanks again for clarification. I experimented a bit by generating a Sine wave in Audacity with at 0.0 dB, exporting it to pcm_u8, encoding that and importing the MP3 back. These experiments back your reasoning (-128.0, then times 256.0).

Fixed in dev.

I missed that multiplier. Yeah, it should be 256.
Using 127.5 would be mathematically more correct for making the peaks symmetric, but zero point is supposed to be at signed zero. The negative side is one higher in all integers but it's not a problem.

MP3 / Re: Low bitrate MP3 (+ unsupported bitrates)
Last post by Klymins -
@itisljar Probably it's the encoder that Adobe Flash CS6 uses for 20kbps and Adobe Media Encoder CS6 uses for all bitrates, and I think it's perfect for not supported bitrates. It'll be great if I can find a way to authorize FhG MP3Enc (looks like it's the encoder that Adobe Flash CS6 uses for other bitrates) as it's buying links are unfortunately not working. I really think FhG MP3enc and Fastencc are literally hero over Lame for encoding tasks with cutoff.

Lossless / Other Codecs / Lossless music stores (files!) not offering FLAC, but other lossless compressed?
Last post by Porcus -
Subject length limit. Question is, are there music stores that offer lossless files for download (not talking about silver discs nor streaming services), and where you can get it in a lossless compressed format - but not in FLAC?

IOW, is FLAC closing so much in on total dominance that if it is offered lossless, then FLAC is an option unless the only option is uncompressed (like Beatport)?
Even in just a resolution where you have to choose another (compressed) format?
(An example the other way around, is Qobuz which cap their WMAL support at CDDA, but apparently supply FLAC and ALAC at all resolutions they offer.)
I'd be surprised if there isn't a single store around offering DTS-compressed DSD-file for sale, that is losslessly compressed and obviously not available as FLAC. But others?

It makes for a facepalm when >8 channel files are delivered as WAVE only, sometimes even one file per channel ;  after all there are compressed format that handle a higher channel count, WavPack has done so since ages, and then there are containers.
(But no "corporate codecs", right?  Both Dolby TrueHD and DTS-HD-MA are capped at eight channels, like FLAC?)

3rd Party Plugins - (fb2k) / Re: foo_enhanced_spectrum_analyzer
Last post by darkflame23 -
Love this component, but just a couple of anomalies:

Even though I have tooltips turned on, I don't get a readout of the note frequency when I hover over a frequency bar, like I did with the old Musical Spectrum. Any way to do this?

Also, the vertical Octave divider lines don't coincide exactly with the actual frequency bars, which look kinda messy. If there's a setting I'm missing, please let me know. I'm trying to get as close to the old Musical Spectrum settings I had, as possible.

MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder
Last post by maikmerten -
Thanks, yeah, seems you're correct. It appears most sources consider the correct bias to be 128. Fixed!

edit: Actually, thinking about this, I may have managed to confuse myself. If 0x80 (128) is the midpoint ("0.0"), and 0xFF (255) is "1.0", then shouldn't have -127 be correct in the first place? Either way, given that the range isn't perfectly symmetric, shouldn't there be a DC bias either way? So isn't "-127.5" technically even more correct?

Also, perhaps I should multiply with 256 instead of 255 to scale it properly?

3rd Party Plugins - (fb2k) / Re: JScript Panel
Last post by marc2k3 -
By default, the first value of multi-values tags is already used...

Code: [Select]
$meta(artist,0)

You can override this by adding this inside the panel as the first line of code.

Code: [Select]
DEFAULT_ARTIST = '$if($stricmp(%album artist%,Various Artists),$meta(artist,0),%album artist%)'
