trying to find one with no luck. i need to get a lpcm file (48k/24bit) extracted from a dvd down to cd (44/16) thanks in advance
You can use SmartRipper to save the LPCM audio to a .wav file (48/96). Use foobar2000 for resampling. Free @ very good quality. http://foobar2000.hydrogenaudio.org HOWTO: (0. Run foobar2000 installer) 1. Load the audio file(s) you want to convert to playlist (e.g. drag'n'drop to fb2k window) 2. Highlight the file(s) you want to convert, Right-click -> Convert -> Settings: - choose a output directory with enough space - leave filename as it is (you'll delete the file anyway after your audio CD is written - right?) - choose Output format: WAV (PCM 16bit dithered) - check all "Processing" options. 3. Highlight the file you want to convert, Right-Click -> Replaygain -> Scan per-file track gain 4. Foobar2000 -> Preferences -> Playback: - Replaygain mode: "use Track gain". :: The pre-set replaygain preamp value is 89dB which is a good choice to avoid clipping :: but might be too low if you want to use your CD e.g. with a too-low powered car stereo. :: Best would be to leave it alone, but If you want a "louder" CD and you set it to higher values :: you shouldn't go > 95dB. - "Use peak info to scale down tracks ..." should be checked 5. Foobar2000 -> Preferences -> Playback -> DSP manager: - Move "Resampler (SSRC)" to active DSPs -> Resampler: - Target sample rate: 44100 S/s - "Slow mode" checked - Internal precision: 64bit Close Preferences. 6. Right-click on the highlighted files in playlist again -> Comvert -> Run conversion
thank you for ur response, i got the wav file from smartripper though one problem is that foobar only recognises the file as a 48k 16bit stream, when i am sure is is 48k 24bit. i got this by going to the file info option bitrate = 1536 samplerate = 48000 channels = 2 codec = PCM bitspersample = 16 that bitrate seems much to high to be a 48/16 stream which is 187kb/s any ideas ?
48kHz/16bit/stereo: 1 Sample = 2x16 = 32 bits 1 Second = 48000 Samples = 1536000 [bold]bits[/bold] Seems like you confused bits with bytes.
agreed my bad, but the fact reamains every aplication tends to think this is a 16bit 48k wav file despite the output filename from smart ripper is "vts_02_([0xA0]_Audio_English_LPCM(2Ch)_48kHz_24bit__)_Delay_-273ms.wav" the track goes 3:49secs or 229 secs and the file size is 63.2 meg this is all very confusing. i am confident it is 24 bit 48k, when i try and play the file i get harsh static, although i can hear some of the song faintly mixed in could it be that smart rippper automatically labels the wav information as 16 bit and something i need to fix, or could the wav be still be multiplexed in an mpg stream ? regards keegan
IIRC there are programs that can convert .wav to .pcm (without header containing information about sampling rate, bit depth, mono/stereo) and pcm back to wav. In this step you have to tell the program sampling rate/bit depth. Unfortunately I can't remember the name, so here's another possibility: [bold]0. Create a security copy of the file[/bold] 1. Open the file in a Hex editor, e.g. XVI32: http://www.chmaas.handshake.de/ 2. The beginning of your file should look like this (Hex view): 52 49 46 46 mm mm mm mm 57 41 56 45 66 6D 74 20 10 00 00 00 01 00 02 00 nn nn 00 00 oo oo oo 00 pp 00 qq 00 64 61 74 61 rr rr rr rr Some Explanations (all numbers are big endian byte order; 00 01 h = 256 d): mm ... mm = <file length> (bytes) starting after last m nn nn = <Sampling rate> (samples/second). Should be [bold]80 BB[/bold] in your file oo oo oo = <Byterate> (Bytes/second). Should be [bold]00 EE 02[/bold] in your file pp = <Bytes/sample> (Bytes). Should be [bold]04[/bold] in your file qq = <bits/sampe (1 channel)> (bits). Should be [bold]10[/bold] in your file rr ... rr = <file length> (bytes) starting after last r Now you have to change [bold]oo oo oo[/bold] to [bold]00 65 04[/bold] [bold]pp[/bold] to [bold]06[/bold] and [bold]qq[/bold] to [bold]18[/bold].

thanks heaps tigre, although im not there yet i used xvi32 to edit the hex on the wav file, i inserted the values and saved the new file i tried playing it in windows media and got no audio although the indicator bar moved, this seemed alot better then getting static i opened it in a few programs such as foobar, headache and awave and both recognise it as a 48k 24bit wav file (finally) but i tried converting with foobar and headache to 48/16 and i still got a wav file of white noise with some audio barely decernable under the noise. id liike to view the 24bit wav file with a wav editor to see if it is static or it looks like a normal wav, meybe the converters are doing there job and converting static or maybe the converters cant handle 24bit ???
foobar2000 is definitely capable of playing back and processing 24/48 audio correctly. So there's something still wrong with the file. Maybe SmartRipper changed the Byte order - but I don't see why there should be silence then. Wave editors: give Cool Edit Pro (30 day trial) or Audacity (free) a try. If you want you can upload the beginning of the file (~ 1-2 MB) somewhere or email it to me and I'll have a look at it. (PM me if so.) Maybe it'd be easier to ask at afterdawn DVD ripping forum if someone knows another program like Smartripper that extracts 24/48 audio stream correctly ...
yeah i got audacity and had a look at the wav ... and no good i was going to suggest if i could put some of the files on an ftp or something how much can i send u (mb) and what format ? i was thinking a complete vob stream to see if u could get anything out of it from scratch
Don't send me the complete VOB. It should be enough to cut 2 MB from the beginning of the extracted .wav file - use something like Maxsplitter or a Hex Editor (cut + paste to a new file).
sorry tigre had to wait and re hire the dvd as my wav files got corrupted i have cleany extracted some new wavs and cut one down so where/how can i send u the file ?
Try using DVD Decrypter as an alternative to snart ripper. It's on these pages at http://www.afterdawn.com/software/video_software/dvd_rippers/dvd_decrypter.cfm I've found this to be a top app, and very good quality obtainable too. HTH
i too am having the same issue when ripping an LPCM track. i use DVD Decrypter to rip the .VOB file to the HD. stream log file info: 0xA0 - Audio - LPCM / 2ch / 48kHz / 24bit / English / LBA: 234133 / PTS: 00:08:06.803 / Delay: -283ms both the picture and audio play fine when i open it w/ my dvd playing software. i use BeSweet to extract the 0xA0(PCM) substream to Wave-Stereo .WAV file. When i try to play the wave file in WinAmp or WMP, all i hear is a loud hiss, and barely audible correct audio. i'm not sure why the audio is not converting from LPCM to WAV correctly. any help would be appreciated.
You guys ever get a resolution to this? I've got a similar problem, trying to rip 24/96 DVD-video and get to 24/96 WAV. Every ripper I've tried sticks it to 16/48. [bold]EDIT:[/bold] Nevermind, figured it out with vStrip(demux) and LPCM24.
EDIT: Nevermind, figured it out with vStrip(demux) and LPCM24. ok i know vstrip but what do u mean by lpcm24 ??? is it a function in vstrip or another program ? thank you ....
