I'm not familiar with that one. My line of work requires conversion between metric and imperial units for the most part. The metric system is an attempt to replace a variety of different measuring systems with an international standard, but imperial units are still widely used and the US tends...

It's a valid opinion, and it's actually very popular in practice for folks to be using target rates of 44.1 or 48 for respective audio and video projects. There are valid arguments for using 96k as well, but it often goes full circle back to Nyquist and then people tend to rehash the same...

The only difference between inches and centimeters is a factor of 2.54. This is an exact conversion. in. x 2.54 = cm cm / 2.54 = in.

Apparently Realtek doesn't publish specs for the 1220 chip/codec. I've seen reference to auto impedance sensing headphone output, multiple channel (surround) capability, and PCM audio support up to 192 kHz. I found a forum where someone was complaining about the sound of the mic input in Linux...

What motherboard audio chipset are you using? Why are you using the mic input?

Here's a paper by Dan Lavry where he's using sine, square and saw waves to describe sampling. He describes the examples as band limited. http://lavryengineering.com/pdfs/lavry-sampling-theory.pdf Of course for any practical purpose that has to do with human hearing it would make sense to band...

If you're generating those shapes with a VCO synth, I don't know why you wouldn't be able to recreate them with a PCM Fourier transform. I have serious doubts about doing that by connecting random gear to a 1/8 mic input.

I bet you could whip out a slammin' version of Louie Louie on that thing!

Basic Digital Sampling: The Nyquist/Shannon Sampling Theorem developed by mathemetician Harry Nyquist and later proven and implemented by Claude Shannon at Bell Labs circa the 1940's is a very complicated piece of mathematics. It's not "simple math", but the basics of it aren't too complicated...

First off, Audacity is a DAW and it has nothing to do with "sampling analog". In order to sample analog, you need an A/D converter such as you would find in a computer sound card, or your Edirol or other audio interface. Once the audio reaches Audacity or any other DAW, it's already digital...

Somebody can correct me if I'm wrong, but an audio CD recorded to a CD-R has a finite lifespan. Commercial, "stamped" CD's aren't nearly as prone to degrade. You need to have backup files of your work. If you burn a data CD with .wav files on it, there's some degree of protection from having...

A standard cassette runs at 1 7/8 IPS. Tascam and Fostex made a number of 4 track machines (eg. 244) that run twice as fast - 3 3/4 IPS. I wasn't aware you could run a cassette at 15 IPS. What make and model is that?

I suspected something like that but wasn't sure until you told us. The 1/8 mic input on your computer is suitable for connection to a computer microphone with a 1/8 phone plug. Your mixer is probably sending a +4 dBu line level signal to an input that wasn't designed for that kind of signal...

The range of human hearing is generally considered to be 20Hz to 20kHz. These are the extreme limits, 20 Hz being a low rumble that's felt more than heard. Low frequencies take more power to reproduce and many typical speaker systems don't go that low unless you have a subwoofer. Even with a...

Sorry, I totally missed what you were trying to say here. Yeah, that console's hooped. I might be able to help you dispose of it. How much would it cost to ship to the left coast? :)

Yeah. It's good to stay objective about it. There's been a lot of debate and controversy between theoreticians and other people working in the industry. You might be able to hear something weird and reliably demonstrate it. Others have, and it turns into a 100 page debate on the internet about...

Greater dynamic range? 16 bit range gets close to the thermal limit. In a more practical sense, it gets close to or sometimes exceeds the noise floor of the analog gear around it (consoles, amps etc...) although as humans we can sometimes hear things down to around -20dB inside the noise floor...

Not really. Dynamic resolution in digital (word length if you prefer) is finite. When it runs out you get quantization error, or truncation. The only exception that I know of is if you're processing the audio and you change the level in exactly 6.02 dB increments (6.02 dB = 1 bit). Truncation...

The Rev. Willie G. is well known for using a peso.

The usefulness of having a discussion on why a 196 dB noise floor is better than a 144 dB noise floor while listening to a file with a 96 dB noise floor on a reproduction system with an 80 dB noise floor is limited unless we consider processing, truncation and the effect of how digital audio can...
