doppler shift


What is the Doppler Shift

The Doppler effect or Doppler shift is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.

Who is Christian Doppler?

Christian Andreas Doppler was an Austrian mathematician and physicist. He is celebrated for his principle – known as the Doppler effect – that the observed frequency of a wave depends on the relative speed of the source and the observer. He used this concept to explain the color of binary stars.

What phenomenon is used in astronomical measurements?

physicist Christian Doppler
This phenomenon is used in astronomical measurements, in Mössbauer effect studies, and in radar and modern navigation. It was first described (1842) by Austrian physicist Christian Doppler.

Where can I learn more about the Doppler effect?

Please help me cross over the subwoofers

This is not strictly a monitoring or recording question but I am having difficulty finding a good place to ask this question since most of the forums I found seem to focus on recording and mixing rather than live sound.

I have begun mixing live sound for a band sort of at random because the drummer cannot run his gear while performing. I stepped in at his house party to cut the feedback and got nominated/appointed sound person despite my hearing issues and tangential background because there is no one else better qualified.

Recording Hand Bells

I have a Roland Tri-Capture interface and Sonar X1 LE software. I have a Shure Beta 57a dynamic mic, an MXL 4000 large diaphragm condenser and an MXL 603s small diaphragm condenser. The 4000 is selectable between cardioid, omni and figure 8 pattern. Low budget, but it has gotten me started. The Tricapture has only one XLR input so stereo micing is out (I think). A friend has written a handbell arrangement and I have offered to record it- overdubbing his multiple takes. We would probably record in church for the ambiance.

To OTB or not to OTB

...that is the question.

Thanks in advance for your time and expertise.

Context: I'm a serious amateur, doing the best I can on a limited budget, no formal training, and an over-the-garage studio. I do straight ahead pop-rock, with drums coming out of Reason Rdk and most other tracks via real instruments. I have some Waves goodies(I use the Renaissance stuff a lot). I have a rack mounted Delta 1010, and an old Tascam m216 from the days of Footloose and Top Gun.

mixdown part 2

Hi all...again!

I've been working on mixing a project band this week witch inclueded 3 songs supposed to be their first demo release. Spending around 25hours on this project and I'm far from satisfied, I just can't get it right! For those who followed my first audio mixdown knows that I'm new to this and have trouble with learning from books and needs someone to show me what I do wrong. This is where you guys enter the picture! :) And all help is much appreciated!

Interesting field recording subjects?

Hi all.

I recently started making field recordings in my spare time just for the fun of it, so far I have made some nice recordings of some trams and I am off soon to record a wind turbine and a few convolution impulses around some interesting architecture in my city.

Feel free to have a listen.
