Audio editing tools - help with adding your own audio clips

[dave]

I hope others will begin adding their own audio clips and/or interesting bits of the LiveATC.net archived audio.

Archives are available at:
http://www.liveatc.net/archive.php
(Please note archives only go back 10 days and are in Eastern Time)

Here is a list of audio editing tools that I use or have tested:

Audacity - runs on Mac OS X, Microsoft Windows, GNU/Linux, and other operating systems...great all-around audioediting/conversion tool.
Available from: http://audacity.sourceforge.net

CDex - ripping and converting tool.
Available from: http://cdexos.sourceforge.net/

That Audacity tool is very cool Dave.

Those who have Sound Blaster Live sound cards; I would reccomend using your WaveStudio (which can also save in mp3 format)

Start>>All Programs>>Creative>>SoundBlaster Live *version*>>Creative WaveStudio

That's also a great tool and has very good output quality

Hey, I don't mean to turn this into an Audacity support forum, so this is just a quick question in the hopes someone has an answer off the top of his/her head (Audacity's website didn't).  If not, don't sweat it.  I am simply looking to contribute to the Aviation Audio Clips board here.

Running Audacity on Windows XP with the Lame_enc.dll properly installed, I have exported an MP3 clip I edited.  

The issue is that this newly exported MP3 clip plays fine in Windows Media Player, but will not play in WinAmp (the latest version).  The clip loads, but when I hit play, WinAmp remains at the 00:00 time and does not advance.  

Any ideas why?  Is there some additional file attribute that must be set in Audacity for WinAmp?

I'm having the same problem.  I found this thread on the Audacity forums.

Turns out it does work if the orginal wav's sample rate is 22050Hz or higher.  The wavs->mp3s that wouldn't play were 11025Hz or lower.

If you increase sample rate (little box in the lower left corner) before you export as mp3, it'll play in WinAmp.

I have a question about the archives. Most of them are complete 29, 21 minutes, but some are 4 or 7 minutes long. Why is that?

I downloaded audacity and that dll file for mp3 enoding, and when I set it to make the audio in mp3, it did but it won't play in winamp. Any tips?

Scroll up two posts.

For my recent recordings I've used an Insignia MP3 player/recorder with audio line input. Device records in WMA (Windows Media Audio). I then use "switch" to convert from WMA to MP3 format since Audacity isn't compatable with WMA. After I get the file converted to the MP3 format, I can do a lot with it in Audacity like editing all the "dead air" and cleaning up the audio. Once you are done editing, export the file back out as an MP3 file.

Both Audacity and Switch are free and are very useful tools.

For those of you who aren't aware, Audacity 1.3.4 has an extremely useful effect called Truncate Silence. It removes all the silent parts in a recording. For example, if you download an archived stream from LiveATC it is 30 minutes long. Depending on the size of the airport, time of day, number of frequencies and such, the recording may actually be mostly silence. If you apply the Truncate Silence effect it converts the file into a non-stop audio stream with no breaks between transmissions. Makes even the smallest towers sound like JFK.

Think of this as VOX, but after the recording has already been made.

Great time saver if you're looking to locate a particular exchange or wish to make your own archives smaller.

This feature was first pointed out here by mechanicalamit in 2006 as best I can tell.

please add "Goldwave" to this list:

http://www.goldwave.com/

I use it. It works.

Goldwave has a 50.00 purchase price, and for goodness sake, if yer gunna pay 50.00, go straight to sonycreativesoftware.com and get audio studio for 54.00 and that program is a REAL editor. its based on the old soundforge platform, and I have Soundforge 7.0, and even audio studio for 50.00 will cook breakfast for you.

These are old Sonic Foundry softwares, and I used Vegas and SoundForge when they were Sonic Foundry. I can attest to the fact that not only are they powerful, but very user friendly, and are industry standard audio platforms.

So if ANY money is going to be spent, take my word for it,

This is what you want... hands down.... (if your gunna pay anything for good software)
