I am new here. Is this the right place to ask this question?
I was using 1.3.9 Audacity. I just downloaded the new version 2x for windows.
I have a CD called Shamanic Dream by Anugama. The first track is referred to as "Earth-Sound with relaxed
heartbeat rhythm. It has some very deep rhythmic drum beats in the back ground that I want to isolate and
record to CD. I looked at the Help section of Audacity but I am confused. Can anyone please help me through
this? The Shamanic Dream can be downloaded free at Youtube if anyone wants to listen to it but when I played it
back on my DVD player I had a hard time hearing that deep drum beat like I have on MY original CD.
I met that I had a hard time hearing the drum beat when I played the CD on
my Lap Top. I hear it fine on my DVD played. Sorry for the confusion. I just want to learn how to isolate
the drum beat from the other instruments so I can record that to CD.
I’ve listened to the beginning of the shamanic dream video, but I don’t know if it was the right song.
Anyway, you can’t separate the rhythm from the other instruments. You can use the lowpass filter (Effect menu) to catch the deep drum sounds (high roll-off and about 200 to 400 Hz).
By the way, the equalizer can also be found in the effect menu (there’s no real time equalization in Audacity).
I am not sure which sounds you want to isolate, the percussion is distributed over the greater part of the spectrum. You can also try to reduce the pad sounds with the noise removal effect (read the help for this).
Thanks Robert. I appreciate your help.
I guess I’m out of luck. I wanted to put together meditation CD
with a drum beat at 3 per second or 3 hz. I wanted to used a DEEP
sound like you would hear with one of those BIG drums in a Symphony
Orchestra. Guess I will be reduced to renting one and recording my own
sound? ( I looked on YouTube and all the drumming sound is very harsh and
sounds like tin. Not what I want. No deep resonate drum beats.
I would not look at YouTube as a paragon of good quality sound. YouTube presentations are Flash Video which compresses the audio and if the original performer used MP3, then the sound has been compressed twice, adding damage each time.
Generate > Noise: brown, 0.8 level, ten seconds.
Effect > Low Pass Filter: 24dB, 150Hz.
Is that the type of sound you’re looking for? That’s earthquake sound. If you can’t hear that “truck going by” sound, then your sound system may not be up to it.
Use the Risset Drum effect from the generate menu.
It gives a nice booming sound for low frequencies (~50 Hz)
Adjust the noise parameters accordingly (to your taste). A decay of 2 s may be appropriate too.
Generate several of those beats and move them with the time-shift tool.
Render those beats into a single track, that represents a whole measure.
duplicate this track and move it to the right, at the start of the second measure. Render those two tracks again, i.e mix them down into one track (track menu).
You can now select the second measure (whithout the decaying tail at the end, where the third measure would start).
Press ‘z’ to limit the selection to the nearest zero crossing.
Go to effects>Repeat and enter how many measures you want the track to last.
The meditation track has more than one pitched drum. You can vary these pitches too. I give you the Hz values for very deep drums, starting at c1 up to c3:
