Topic: DiskWelder Bronze 1000

[SClassical]

Anyone here has the DiskWelder Bronze 1000? Can you see and edit DSD DFF files using this program? I heard you need to upgrade to the Chrome II to do DSD>PCM convertion but was wondering is DiskWelder Bronze 1000 alone allow you to see a DSD DFF file as a wave form...

Anyone here got DiskWelder Bronze 1000? I'll like to ask a few questions.

Bronze 1000 will allow you to convert DSD to PCM 24/96, 24/48 and CD. It can only process and record to DVD as DVD-Audio or CD. You can't save the converted file to hard drive and no ability to see the waveform or edit.

I got got DISCWELDER BRONZE in the mail and loaded her up,

added my 24/48 tracks to make my first DVD_AUDIO disc and when it finished it doesnt play on any of my dvd players, I clearly see the AUDIO_TS files, I try to play them manually thru windows media player ( cause that works with video_ts files) but still nothing.

I also notice discwelder gives me a empty video_ts folder.

what am I doing wrong?

Can you tell me if the Bronze 1000 convert DSD DFF to 24/192 without a problem? I like to check your DSD DFF file with my one if you don't mind. Only a few sec of DFF music will be fine for this test. At the moment I am converting DSD DFF to 24/192 (using AudioGate). I see a lot of fuzz/noise in my PCM file when looking at the wav form in my editing program (SF8). So my test is to find who is causing the fuzzy wave problem - if it's my DFF file or my audiogate program? This is the question I'll like to find out.

If your DFF looks perfect after I've done the conversion in AudioGate then I know there is something wrong all my DFF files (meaning something wrong with my recorder - needs a new firmware). If I still see this fuzzy wave after converting it to 24/192 then I know it is my audiogate program which is causing the problem (needs new version update).

Can a small DFF file be sent in an attachment? I'll PM you my email address if you don't mind me doing a test with your small DFF file.

dointhatrag ,
DISCWELDER BRONZE make true DVD-A format, so you can play in DVD which support DVD-A format. You can not play it in any DVD player.You must try in machine for DVD-A and SACD, usually they play DVD too.

Discwelder Bronze 1000 will only convert to 24/48 and 24/96 as DVD-Audio. No 24/192. I can look for a very small DFF file I might have and email to you. I think I can only divide a DFF file on the Tascam DSD recorder until I get AudioGate.

Are you sure about that?

I think that is the Chrome II ver.

I have chrome II but not the Audiogate, not untill my MR-1000 arives.

[SClassical]

With Chrome II, you still cannot convert DSD to 24/192?

Thanks MattH! If you have a DFF file only 1-2 sec that will do fine (which is not made from the Korg recorders) that will tell us who the culprit is (the recorder making a faulty DFF file or the AudioGate doing a bad conversion).

Yup.  Most DVD's are 24/96 or 24/48, so the choices are limited to these two.  And no it won't convert to 16 bits directly.  24/48 is the default.

I would still like to see the results of the audiogate test.

Thanks MattH for the few sec sample!

I tested the DFF and have some interesting results..

I converted MattH's perfect DFF to 16/44.1 and also to 24/196 using the AG program provided by Korg and looked at the PCM wave form in SF8.

Both wav looks similar so it seems there is a fault in the MR1 making the DFF file. But this is not the complete story...when I checked the first few mini second of the begining of the track (where the softest part of the music was) on the left channel the max peak was -10.7dB for the 24/192 vs -12.3dB for 16/44.1. Is it normal for a program to change the peak height when converting it to different bit/sampling rates? If all the peaks should stay the same than it seems as if both the MR-1 and AG needs to have an update (for the AG) and new firmware (for the MR-1).

I sent the original DFF file I got from MattH to Jeff to do a test, too. Maybe he will reply with his results.

Hello folks:

I have not been "hiding", but until I get answers from Korg Inc. I couldn't really help. Now I can.

The issue of the noise is due to the nature of the Sigma-Delta noise-shaping that happens with the technologies we (and others) use. The MR recorders use the Texas Instruments PCM1804 A/D converter - a highly respected component. You can refer to its data sheet (page 12, 17) for more information on the structure and characteristics of practical sigma-delta modulators.

http://focus.ti.com/lit/ds/symlink/pcm1804.pdf

The anti-aliasing filter used in AudioGate for 2.8MHz DSD -> 192kHz PCM conversion is similar to the filters used in other company's DSD->PCM conversion software already in the market. These are designed to keep the information loss to a minimum rather than to reduce the out-band noise generated by sigma-delta modulators.

But we recognized the issue you are experiencing, and have designed 2 new filters for the conversion based on other methods, which will reduce those out-band noise. They will be included in the next version of AudioGate (ver.1.0.1) which will be released in April along with the support for Windows Vista.

We appreciate that you want and need to make these conversions and just ask for you to be a little patient while we finish implementing and testing the software.

We have also just finished a new OS for the MR-1 (1.01) which will get posted to korg.com tomorrow. It fixes a small bug which caused the System Clock to not always keep accurate time.

I know it's not related to this discussion, but this is as good a place to let you know.

Thanks for your patience - we are listening and watching. But again, many times I need to check with Japan to get answers for you.

Regards,

Jerry
