..........and my thanks to both.

...from a true novice at this.


To Aleksey & Neil:

Thank you both for guidance.

Several moequestions if you don't mind, for this novice:

(1) What is 'ULTRASTEEP MODE" and when to select it

(2) What is 32-bit float?  CD (i.e. redbook) are 44.1/16 bit.  I'm going to take 88.2 at 24 bit and convert to redbook so I can import into SURCODE CD-DTS.  Is 32 bit float a choice to consider for this?

(3) One more choice I don't understand is "NORMALIZE dBFS.  When is it preferable to use this option.

....and BTW: the full pro version which I purchased seems to be running the conversion much faster than the free version.

THanks in advance for answers.


Ooooops sorry for being a 'dunce'

I found the answers.


4-ch-guy: ....and BTW: the full pro version which I purchased seems to be running the conversion much faster than the free version.

I've forgot to mention that r8brain PRO is maximally fast at whole number conversions (88.2 to 44.1 is conversion with a whole-number downsampling factor of 2).  So, you've probably saved a lot of time with PRO version, beside having a better quality.

(conversions from 96k to 44.1k are not as fast of course)


4-ch-guy: I am new to manipulating digital streams.  I have music recorded in 4 channels digitally, onto an ALESIS HD24XR.  I was able to import as .wav files to computer (WIN XP-Pro).  They sample at 88.2 kHz and I need to get them to 44.1 kHz.

4-ch-guy: I am hoping that either one of your r8brain products will do the job for me, as that is all I need to do.  Incidentally I tried using Audacity to do this.  When I took the 88.2 file and tried to covert to 44.1 it clearly played at half speed.

4-ch-guy: So…will your product(s) convert 88.2 to 44.1 successfully.  Thanks in advance.

4-ch-guy: Also will r8brain products take a multi channel stream in dts and send it to CD?

Hey 4-ch-guy, drop me a PM.  I think we also want to discuss Crown Electrostats.


Once a stream is encoded to DTS, no sample rate change tools will work on it at all - period.  It will need to be decoded again, resampled & re-encoded with the resulting loss in quality.

Also.

DTS-CD can do more than surround - and one of the tricks to this is to feed the encoder 24-44.1 files, not 16/44.1! - it can do stereo on DTS-CD at 24/88.2 resolution.

Aleksey:

I noted that marceljs wishes me to send a PM.

Can this be done thru your site?

If not can you help us reach each other.

You may certainly send my email or other contact information.

Thank you....and I have found your SRC program perfect for my needs.

THanks


marceljs, please send me a note to info@voxengo.com : I'll forward your e-mail address to 4-ch-guy.

4-ch-guy: Minnetonka makes a product called CD-dts which will import .wav forms, but only at 44.1, which is why I was curious about r8brain.

You may also want to look at the Master Audio Suite from DTS.  They have lowered the price to $249.  In surround you can have 44.1 on DTS-DC and 48k or 96k on DVD.

I don't think so!!

The DTS-HD MAS is not even close to $249.

It's much more in the region of $1500.

I believe you must be thinking of the DTS-DVD encoder from SurCode.

That is indeed only $249, and it will certainly not encode anything at 96KHz.

It is also over 6 years old now, and the algorithm is well out of date - the Nuendo DTS encoder is audibly better, then the DTS-PSE is better still, with the best of all being the DTS-HD MAS (in legacy or DTS Music Disc mode for this concersation's purposes).

DTS works like this:

DTS-CD can be in 44.1KHz or 88.2KHz in stereo or 44.1 in surround.  These look like straight `16/44.1 stereo WAV files because there is a fake PCM header allowing the file to be written as an Audio CD.

DTS on DVD must be either 48KHz or 96KHz - if you have either the DTS-PSE (obsolete) or the DTS-HD SAS ($800) or the DTS-HD MAS ($1500)

DTS-HD is the new type and requires the full DTS-HD MAS encoder for Master Audio (lossless) or the MAS/SAS for DTS-HD High Resolution (which is a 3000kbps stream)

Sorry to point this out, but seriously - your prices & details are wrong.
