Topic: 24 bit vs 16 bit

[gusbud1]

I am finally upgrading my dat to a solid state recorder, but truthfully I know nothing about 24 bit recording.  Can 24 bit recordings even play on anything?  At one time I heard it was mostly for archival purposes, until technology caught up.  Is that still the case?  If I record in 24 bit how do I process it or resample.  I am sure there is alot of information out there on the subject, if someone would be kind enough to point the way.

Thanks

all the questions you ask have been discussed many times over here. playback technology exists and is coming down in price, music is burned onto various formats of DVD. pretty much all the major audio software programs have dither/resample functions.

If you record in 24bit and want to listen on a CD, you will need to first dither and resample (assuming you were sampling > 44.1).  Or you can burn them as DVD-Audio and listen at the full resolution.  Of course, you need a DVD player that accomodates DVD-A.  You can also listen to them on your computer, but it's nice to have some kind separate D/A to keep noise issues from occurring

Check the playback forum or the search function.  There's oodles of info here and I'm sure others will have better, more in depth responses than I

I've been doing some testing and thinking about this, since I have the ability to record at 24/96 if I want...
I'm starting to think 24/44.1 is the way to go. With 24/44.1 you only have to dither, no resample for making CD's. I hear a difference between 24 bit and 16 bit, so it do believe it's worth moving up in bit rate. I haven't seen or heard the benefits from moving up in sample rate.

it's my understanding to burn to DVD it needs to be at least 48, so you would have to upsample in the future to put the 24bit on DVD. please correct me if I am wrong. it only takes a few minutes to resample.

Hmmm... I'm not sure about that. I can't play DVD-A's. I can make an audio only video DVD and play it in my DVD player. But, I'm not sure if it has to be 48kHz.

As far as one more step, I'm a minimalist and think it's best to do as little as possible to the audio once it's captured.

I'm pretty sure that you can put 24/44.1 on DVD-V audio discs.

Teddy posted a cool article here.  It has more to do with frequency than bit rate, but it's all part of the learning curve.

a DVD-Video disc (such as one burned with "audio DVD creator") has to be either 48 kHz or 96 kHz.  the DVD-Audio format and allows for a whole variety of sample rates: 44.1, 48, 88.2, 96, 176.4, or 192 kHz.

Ah, I had it backwards

I've been running 24/44.1 for the past month and loving it. I don't really have a 24-bit playback option, but in the future if I do, I save all of my originals/masters. I've been running at 24-bit mostly for the extra headroom, which is nice to have. On the sampling front, I personally can't really tell the difference, so I like not having to resample in my workflow. However, if I know I am going to sync to MiniDV or encode DV video to DVD, I'll usually record at 48 because that's what DV/DVD runs it's PCM at typically. Anyway, my main point is that you may want to run at 24-bit for two main reasons: (1) headroom, and (2) archiving for possible future use. That's my two cents...
