...support of 32 bit audio data. The request has been around since 2008. Had two inial impressions: * Would adding this break brackwards compatibility too badly? Obviously decoding of 32 bit encoded data would not work with older versions of flac. * This is nuts. 24 bits has a dynamic range of ~140dB which is roughly the difference between a quiet whisper in a quiet room, to the sound of a jet engine at 10 meters. Surely that is enough? Thoughts? Cheers, Erik -- ---------------------------------------------------------------------- Erik de Castro Lopo http://www.mega-nerd.com/

...t ? If so why does the table have only 256 elements ? This would imply that the "Y" value decoded from the bitstream should has a range from "0" to 256. ? Does the encoder ensure this ? In section 1.3.2.8 of the vorbis specification "However, floor vector values can span ~140dB (~24 bits unsigned)" . What is this referring to ? Is it the final ( dequantised ) floor vector ? warm regards, Sameen -- ___________________________________________________________ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm -------------- next part ----------...

I know that Josh at some point added a second residual coding method (rice2) to support 24-bit, but that only broke backward compatibility for 24-bit files back then. > * This is nuts. 24 bits has a dynamic range of ~140dB which is roughly > the difference between a quiet whisper in a quiet room, to the sound > of a jet engine at 10 meters. Surely that is enough? Yes, this is nuts. First, 24-bit is already overkill, as there is no hardware (ADC or DAC) that can handle more than 120dB of dynamic range a...

I have some questions about how a sample is encoded in Vorbis regarding the dynamic range. I try to figured it out by reading the Vorbis spec and I failed. But I found this quote from Monty: ?Vorbis, BTW, can handle, for sake of programming simplicity, >200dB range. Just for kicks.? [1] It's still unclear to me what that means. Should I think of Vorbis as a floating-point format or a

...have noted, there's movement towards 32-bit audiophile delivery. FLAC should be the 32-bit delivery format of choice. > > On Sat, Sep 26, 2015 at 10:36 AM, Martijn van Beurden > <mvanb1 at gmail.com> wrote: > > > * This is nuts. 24 bits has a dynamic range of ~140dB which is roughly > > the difference between a quiet whisper in a quiet room, to > the sound > > of a jet engine at 10 meters.

I'm on Centos 5.5, and would like to use sox to strip out any periods of silence > 5 seconds from a batch mp3 audio files. Googling I found sox, but it does not seem to support mp3 files by default. The man page says: .mp3 MP3 Compressed Audio MP3 audio files come from the MPEG standards for audio and video compression. They are a lossy compression format that achieves
