MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder
Last post by KevinB52379 -
I tried that build and I get about 300x from the external hard drive where my FLACs are and converting to mp3 to the internal SSD using foobar2000 and Helix. 

I am copying the FLACs over to the internal SSD and I'm going to try using foobar2000 to convert totally from internal SSD drive...so the source will be the internal SSD and the destination will be the same internal SSD.

My system is a PCIe Gen 3x so I didn't bother paying more for a PCIE gen 4 drive.

There were no BIOS updates.  The latest is from October 2023 and that is what I have installed.

I'll let you know how this conversion fares.

Here is an x64 compile that is built with the slower compiler option -O1 that is only minimal faster as the win32 by Case.
The idea is that something overpaces your config.
Also a test with files encoded from the local SSD without USB in play can help to get an idea.

I'll look for a BIOS update.  The one I currently have installed is from October 2023.  It's an HP system.  But, I feel that if it was a USB problem, wouldn't it be happening with Case's version as well? 

I'll search on HP's website for a newer BIOS offering for my model.

Thanks!

MP3 / Re: Low bitrate MP3 (+ unsupported bitrates)

@AiZ How can i get this with ~12kbps (ABR does not do that)? And, which program is shown in this screenshot? Addition: By "ABR does not do that", i mean: Let 8kbps frames be letter A and 16kbps ones B. ABR does something like "ABABBAABBABAABABBA" but i want "BABABABABABABABA".

MPEG-2.5 Audio Layer III: 8, 16, 24, 32, 40, 48, 56 kbps

These are the bitrates for MP3 CBR mode. There is no 12 kbps among them. Thus, to get 12 kbps file, which can be played back on a wide range of audio equipment, you have no choice but to use VBR mode (or ABR as a variation of it) so that some of the data is compressed at a lower bitrate and some of the data is compressed at a higher bitrate, producing the output that is as close as possible to the bitrate you specified.

If not specified, LAME may sometimes resample automatically when faced with extreme compression conditions (like encoding a 44.1 kHz input file at 32 kbps).  To disable this automatic resampling, you have to use --resample to set the output samplerate equal to the input samplerate.  In that case, LAME will not perform any extra computations.

@Kraeved Much thanks. So, is manually setting the cutoff frequency possible with this? I wrote "--lowpass 3500" but this also changed the sampling rate to 8000Hz. It must be 11025Hz otherwise i can't import this file to Flash. Also, can this tool make 12kbps CBR (18kbps and 20kbps files were CBR)?
