Other Lossy Codecs / Re: How to add new modes in WMA 9.2?
Last post by Apesbrain -
You could do it via commandline:
Code: [Select]
cscript.exe wmcmd.vbs –input inputfile.wav –output outputfile.wma -a_mode 0 –a_setting 56_44_2
-a_mode mode_number
Specifies the encoding mode for audio content. You can use one- or two-pass CBR encoding (-a_mode 0 or -a_mode 1, respectively), or a VBR encoding encoding mode: quality-based (-a_mode 2), bit rate-based (-a_mode 3), or peak bit rate-based (-a_mode 4). For more information, see Using CBR or VBR encoding.

-a_setting bitrate_samplerate_channel
Specifies the audio bit rate, sample rate, and channel setting for encoding. Or, if you are using the Windows Media Audio 9 Professional or Windows Media Audio 9 Lossless codecs, -a_setting also specifies 16- or 24-bit encoding, as bitrate_samplerate_channel_bitspersample. Use the -a_formats option to view the settings supported for each codec. If you are using the Windows Media Audio 9 Voice codec, the default value is 12_16_1. If you are using the Windows Media Audio 9 Professional codec, the default value is 128_44_2_24 (unless you are also implementing a quality-based VBR session, in which case the default is Q75_44_2_24.) If you are using the Windows Media Audio 9 Lossless codec, the default is Q100_44_2_16. If you are encoding uncompressed content, the default value is 705_22_2. For all other scenarios, the default value is 64_44_2.

MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder

Okay, I now threw out the 8-bit resampling code - now all sample formats are handled by the same 32-bit float resampling/conversion steps. https://github.com/maikmerten/hmp3/commit/a07d35c3dbe5acb22e1301c27df2dfe92dccb908

I also adjusted the Makefile and VisualStudio project files (by hand). Seems the automated builds on AppVeyor still work ( https://ci.appveyor.com/project/maikmerten/hmp3/builds/49846828/artifacts ), so I assume the VisualStudio project file surgery went okay.

thanks !!!

MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder

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?)
