engines sound and audio editor program

[lulu]

I'm looking for an audio editor program to build some engine sound.

I know 'audacity' and 'free sound editor'.

From my info about how to make those sound
I need something that is able to play sounds tracks and record they: SIMULTANEOUSLY and  INDIPENDENTLY between their in TIME

Any suggestions?

Sorry, I didn't quite understand what you meant by

SIMULTANEOUSLY and  INDIPENDENTLY between their in TIME

, but I've been using Audacity for creating engine sounds.

This is my Brewster sound, which is based on a youtube clip of a T28Trojan and mixed with the sounds of a circular saw and jackhammer, slowed it down to simulate the lower rpm and added some beef into the lower frequences to compensate the loss of basses of the camera mic. There are no more flyable Brewsters left, so I took the closest engine I could find, calculated the rpm difference and added the extra sounds based on pilot interviews. By zooming in and searching the zero points I could make the sound clip continuous. Here's the start sound I made for it, using the abovementioned YT clip and adding original hand driven inertia starter sound from another clip, showing the start of a Bf-109E. Again, I zoomed in to find a matching zero point with the running engine sound. Oh, and of course I changed all sounds to mono before mixing anything.

I used 'audacity' but It does not play sound indipentently.

Good work on Brew's engine.

I still don't quite get what you mean by playing independently. Do you mean you want it to play only certain sounds in your mix?

BTW, added the link to the start sound above...

I think he means multi track editing. Lulu, try LMMS (linux multimedia studio) it has multitrack capabilities for free.

Other than that I know only paid software. I personally use Reason/Record 5 which has awesome mixing, vocoding, sampling, effect etc. capabilities etc. Reason5 is something like 300 bucks in the store.

Audacity is a multitrack editor ...

Looking for p51 engine sound, I found that planes engine sound is a 'sum' of:

Propeller(1) + engine(2) +  cobustion (3) + wind(4) + something else (?).

Problem:

(1), (2), ..., (4) can have different legnths.

Program like 'audacity' can play simultaneously but not independently from their different lenghts.

Program like 'audacity' start to play all the sound together but the most short sound will end before the rest!

Solution:

I need that (1),(2), ..., (4) run independently from their lenghts in such a manner to obtain a kind of
differential sound loop.

I want to do something like this:

Sound forge does this I often blend 2 or 3 sounds together to create depth.
It can also add length or trim it so all sounds are uniform. hope my info helps

You can do that with Audacity, too. If the sound sources are of different sample rate, the first thing is to convert them to be equal and the second is to change their speed back to original. I mean, if you have a sound clip of 44100 Hz and you want to produce a 16000 Hz sound, you can convert your source, but its speed will drop and its length will raise. So you'll have to multiply the speed by 2.75625 to get the original pitch and length (44100/16000=2.75625). The effect "change tempo" will retain the original pitch, whilst "change speed" doesn't. Their values are given as percentage, so adding 100% equivalents of multiplying by 2 and similarly adding -100% means dividing by 2. Very basic maths, as you can see, but it may take a while to get used to. Listen to my Brewster starting sound: The original inertia starter video was several minutes long, as was the Trojan video. I stopwatched the ingame time for the Brewster start with exhaust puffs and such and worked accordingly with the mix. I added silence to the actual engine sound and tried to find a significant part of the inertia starter into the beginning, fading it in. Remember, the sound wave in the end of the start clip had also to be matched to the one of the actual engine sound, meaning that it had to end in a zero point and coming from below because the engine sound starts by raising from zero.

Another important thing concerning AH sounds is the file size. Having long sound clips with lots of kilobytes and a high sample rate is asking for trouble. Look at the sample rates and lengths in other sound packs and work accordingly.

Actually its kind of like image editing. You dont want to use small files at the very beginning. A good digital recorder will sample at up to 192 kHz but probably a good rate to maintain originals is between 44 and 96 kHz. Get them cleaned up at the very beginning also or you will introduce things like the washboard effect and bucket reflection that you can hear in just about all of the sound packs. The reason is they are using tracks that have already been resampled too low for more processing. Having a track that is too long is actually a good thing because you can "recenter" the portion you use in order to avoid issues with the other tracks like overlapping peaks which might cause clipping or distortion. Then learn how to get the mix to loop properly which is really nothing more than proper cropping technique.

WOW! Chalenge, you really gave me a lesson in the English language! In just a few sentences you said all I ever wanted and more.

the planets must be aligned i agree with chalenge

I dont think any one editor is enough anymore. I used GoldWave for a long time before I bought another program but it doesnt do multitrack either. The effects are in some cases better than more expensive products like SoundForge. Audacity has for a long time had a problem with invert mixes where it introduces terrible noise which is far worse than a noisy crowd. Audition is my primary editor but it also has issues with noise if you open too many files at once or edit over a long period of time. So you end up using them all.
