1-Bit Professional Mobile Recorder : diginfo

Korg is now releasing the MR-1000, the world's first compact 1 bit professional mobile recorder that can reproduce original sounds unlike ever before.
The MR-1000 is a professional master field recorder that is compatible with various PCM (Pulse-code modulation) formats as well as 1-bit audio including DSD formats used for SACD or Super Audio CD, an optical disk format that provides high fidelity digital audio reproduction.
Pulse-code modulation is a digital representation of an analog signal and DSD (Direct-Stream Digital) is a system developed by Sony and Philips for recreating audible frequencies to store audio signals on digital storage media. The difference between the two lies in the method used to compute the calculations for original sound data. The DSD 1-bit technology calculates sound frequencies using only zeroes and ones and can therefore pinpoint original sounds as close to the original as possible. However, PCM 24 bit technology requires that sound be set at the right numerical value in a sound range between -8 million and plus 8 million, so even with the best CPU, mistakes are bound to be made.
DSD has three formats, DSDIFF, WSD, and DSF, and the MR-1000 is the world's first mobile recorder to support all three formats.
The MR-1000 weighs only one kilogram and is easy to carry with its half rack size. It can be easily connected to a PC with a USB 2.0 cable, and with audio gate software, can convert just about any format. You can even listen to recordings in the car for example.
The MR-1000 is priced at 147,000 yen.

I love this field recorder I use it for most of my sampling projects.

and what's all this nonsense about 24 bit and 192khz talk .

blah blah blah!!!

[johneymute]

oke we get it to the point,the sounds is recorded at 24bit 192 khz,but is stored as 1bit dsd,a format wich is a losseless compression format.

the dac only has to guess between 1 and 0,s so there,s less chane of a mistake.

however redbook audio is stored in 16bit format as non compressed 16bit pcm at 44,1 khz.

but the dac has to make a guess out of 16,536 combinations,so the chance of a mistake is bigger and it,s also less natural.

@Tastenzaehler The mistakes in PCM recording happen when the actual level of an audio signal is not a whole number. Like the video said, PCM chooses a value between -8 mil and +8 mil. If the actual value of a sound wave is, lets say, 100000.5, the cpu has to round up to 1000001. This is the error.

@johneymute Hey Johneymute,

I think you are a little mistaken. DSD is not 24 bit recording - it is actually 1bit.

When I first saw the title I thought what a hell - 1 bit PCM audio would be square waves - haha.

But then I saw that it's some other audio formats - not the resulotion of PCM audio.

how do you unplug a optical audio cable?? its stuck in my tv...

[izerra]

what is this thing good for then?

[wado1942]

Since it's descrete measurements of a continuous waveform, it misses more of the audio than it captures.

BTW, unlike what the video claims, Sony/Phillips did NOT invent this format. It was invented in the 60s and first mass produced by DBX in the early/mid 80s.

[Tastenzaehler]

what are the mistakes the cpu makes to the audio range???

very cool site great info
