Is RH_AMP the same as RH_NOISE_CALC ? - Original Message - From: "Robert Hegemann" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, September 22, 2000 10:57 AM Subject: Re: [MP3 ENCODER] CBR quality improvement Naoki Shibata schrieb am Fre, 22 Sep 2000: Hi, I've just committed some changes to --nspsytune that improves CBR quality though encoding speed becomes a lot slower. Changes I made are following: 1. Use -X1. 2. amp_scalefac_bands() amplifies only one sfb at a time. I think quality improvement is easily noticable. Encoded quality of applaud.wav is now very close to that of mp3enc3.1. -- Naoki Shibata e-mail: [EMAIL PROTECTED] compile LAME with RH_AMP, call it with -Y and you get similar results. It's already there for a while and features some better short block noise coloring. -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )

Hi Naoki. changes to --nspsytune that improves CBR quality Would that include Safe-VBR mode as well? Shawn -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )

Naoki Changes I made are following: Naoki Naoki 1. Use -X1. Naoki 2. amp_scalefac_bands() amplifies only one sfb at a time. Robert compile LAME with RH_AMP, call it with -Y Robert and you get similar results. It's already Robert there for a while and features some better Robert short block noise coloring. Improvement of CBR quality is achieved only when both 1 and 2 are turned on. RH_AMP with -Y option only turns on 2. Please listen with your ears and compare. Shawn Would that include Safe-VBR mode as well? Currently, ABR is not included. -- Naoki Shibata e-mail: [EMAIL PROTECTED] -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )
