APDs are back


Recommended Posts

DCI.org just put a link up for some 2014-2015 APDs and some 2015 videos.... it is a start!!! :)

See the FAQ

https://marchingmusicdownloads.com/faq/

I find it interesting that the bundle download of APD for 2015 is $10.00 more expensive than the actual physical cd for some reason.

I prefer the download but I don't want to pay 10 bucks more or deal with the shipping and owning the actual cd now when I would just rip it onto my iphone..

They are offering uncompressed formats with the downloads. Waaaay better than CD quality.

I'll echo the comment about lossless files, There's a pronounced, noticeable difference on quality between a CD and lossless. Playing $10 more for lossless? That's a steal.

It's an improvement. Must we always ##### about things? Should they all go away again?

I thought lossless meant CD quality, not better than CD quality. CD bitrate is 1411 kbps. Lossless just means the sound is not compressed, so its the same as the CD. Is this correct?

Now, Hi-Res Audio is another matter. Those are 9216 kbps, which are better than CD quality. I don't think DCI is offering Hi-Res audio though, just lossless.

Either way, I'm glad they are offering this. I just wish they would sell the regular season APD's as well so we could have recordings of the corps throughout the summer. But I fear that the licensing fees have pretty much destroyed that option from ever being offered again... :(

So, my limited understanding of it:

You have sample rate, and you have bits per sample. Once you have a sample rate above 2x the highest frequency, you can perfectly reconstruct the signal, aka audio (nyquist theorem, it has to do the DFT of the signal). YOu do get some aliasing, but assuming you filter the incoming signal, sampling above 44.1khz does nothing extra. Then you have the bits per sample. This is how quantized a signal gets. So if it was one bit, then you signal is either max amplitude or zero. 2 bits, you can have zero, 1/3, 2/3, and full. CD's use 16 bits per sample, which means it can assign the amplitude of the signal to one of 65,536 levels. Blu-ray and DVD can support 24bits per sample. Multiply the sample rate by the bits per sample and you get the raw bit rate. CD's sample at 44.1Khz, but 2 channels.

Lossless is something different. A drum corps show would be about 100Megabytes at this rate, but, you can use patterns and other tricks to lower the size. There are 2 ways to do that, one is to lose a bit of information for great gains in size reduction, which is lossy, and the other is to have a smaller ratio, but you don't loose any information (interestingly enough, there are certain combinations that will increase in size from these algorithms, its just people are clever and make those combinations really unlikely to occur).

The files you rip from a CD are generally 192kbps, unless you rip them to be lossless. If you do that, then you are golden and are getting probably the highest quality sound reasonable.

Just be careful with bitrates, because it only matters if the bits per sample are increasing, not the sampling frequency.

I'm familiar with lossless audio but the source of the lossless audio holds greater meaning. A file can't be better than the original so if the lossless files are created from the CD it is no better then the original.

If these lossless files are created from the original raw wav files then I agree with you. I'm just not sure I care as much versus storage space on my iPhone.

Definitely not hi-res audio

edit: hi-res, not hi-def
