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

3rd Party Plugins - (fb2k) / Re: foo_vis_spectrum_analyzer
Last post by pqyt -The Amax in the skippystudio explanation refers to maximum amplitude of the signal, which is 1.0. Their graph also perfectly shows that real RMS can't be as high as peaks.Sorry @case but I'm not going to take your word for it. Removing the division causes all the test files from SOS to have a dBFS reading that is 3dB higher than their expected result. Even the tone://997 reference is wrong.
So remove the division by Amax and things will be correct. Real RMS shows correct RMS, and the checkbox enables the 'RMS+3' mode.

MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder
Last post by KevinB52379 -For some reason your version from a few days ago (5.2.2) works flawlessly and fast. I have an AMD Ryzen 7 5700g, Windows 11, 32GB DDR4 RAM and 1TB nvme SSD if that matters.
The last version of helix to work from Rarewares from about March 21 I think? Every version after that either 32 or 64 bit, runs really slow, and hangs the system and just makes everything slow down to almost a crawl yet CPU usage is about half.
Thanks so much!

Then add dsp in converter preset options:
-resampler(dbpoweramp) = 11.25k
-downmix stereo to mono
This has given me a mono 16k cbr mp3 file tested OK with speech. 8k was too low quality for me.

MP3 / Re: Low bitrate MP3 (+ unsupported bitrates)
Last post by Klymins -16kbps MP3 is much easier to listen for me because it's "simplified" by the MP3 algorithm and high frequencies are in relationship with low frequencies as they are just reflections. 11025Hz is a magical sampling rate for me. And, i don't have any hearing issues, my both ears can hear higher than 16kHz.
I can accept a little bit lower quality than 16kbps MP3 by Adobe Flash CS6 and if this quality can be achived with ~12kbps that will be good for me because this means i can use more/longer musics.

MP3 / Re: Low bitrate MP3 (+ unsupported bitrates)
Last post by jaybeee -Or is this for some project you're working on to create low bitrate audio that is acceptable for the project?
If it's the former then I cannot understand why you'd want to go so low with the bitrate when the audio is clearly so much worse than the lossless source; i.e. it is not transparent at all and unless one has a hearing issue (maybe you have?), then it seems nonsensical to me.
I have some aac music audio files that were encoded by someone else at ~64kbps and they sound very good for such a low bitrate (the excellence of modern codecs at low bitrates shines). But for personal listening (via my mobile using headphones and also connected in my car) I use Apple aac (qaac) with (T)VBR q64 which aims for 128kbps. But I dare say aiming for 64kbps for me would be acceptable in the car for instance.
Of course, there's no issues in discussing this desire for such low bitrates in an mp3 for example and it's an interesting subject. I'm just confused as to why - if it is indeed for music listening pleasure - you'd want to go so low when you'd almost certainly be able to ABX between it and the source lossless files... and between say even 64kbps mp3s and aacs.
