Server-side Audio Editor - iis

I am looking for an audio editor that we can use server side (ASP + IIS)
We want users to be able to upload an audio file, and then offer a 10 second teaser clip to other users for download.
Ideally I would like our application to be able to specify Input and Output Filename, Start and End time (or Duration), and be able to fade-in and fade-out, and equalise the volume.
Maybe some audio editors have a batch edit facility, and it would just be a question of installing on the server?
All the keywords I have tried putting into Google have led me on a wild goose chase, hopefully someone can help me with suggestions. Thanks.

Try ffmpeg!
http://ffmpeg.org/
I've used it for all sorts of manipulations of video and audio.

Raw sound files editors, 8bit

I was wondering if anyone knows how to open and edit a raw sound file (raw unsigned 8-bit).
I am making my own game and trying to create original 8-bit music.
I could not open SoX, and all other editors I have cannot play these frequencies correctly.
I appreciate all help.
try using beep box. you can recover work from the past 30 days. or, you can try import a .mid file. you can have 4 base notes, and set the instrements to 8-bit sounds, crunches and waves. hope it works for you! --> beepbox.org or search it up if this link doesnt work

Auralise Audacity annotations / Generate audio click track from list of click times

I'm trying to annotate musical audio file in Audacity and then "listen" to annotations along with the file to check they are placed right. I haven't found an Audacity plugin that does it, but when I export Audacity labels I get a file like:
3.558390
4.248639
4.910771
5.632766
6.349320
...
This time of file (in seconds) where point labels were placed. Maybe there's a tool (or maybe you can do it programmatically (in C++ on Linux preferably)) to easily generate such a click track? I would be then able to mix it with original file and listen to inspect it.
I've found two ways to solve this issue:
Write your own plugin in Nyquist (what I'm trying to do), I received great help on the Audacity forum:
http://forum.audacityteam.org/viewtopic.php?f=39&t=68752
Use Sonic Visualiser:
http://www.sonicvisualiser.org/
This program combines two important features: insertion of annotations when audio is played and auralisation (different sounds available).

Quicktime Object Embed Without Buffering

I have a site [here][link removed] (IE8 and Google Chrome 5 only).
I was wondering for the Quicktime object if there was a way to not start buffering unless the user clicks the play button?
I hope to insert other movie files in the future and having them all buffer is not reasonable unless there is no way of getting this done.
thank you.
I found this. It seems like it may not be possible.
the method is on quicktime player use edit and beginning point.
set at the beginning and it starts from the begining and buffers as the movie is played.

continously add picture to video

Every x minutes I grab an image from a network-cam. Now i want to add this picture to an existing video file - on the fly.
I don't want to keep numerous image files and then encode them once in a while with e.g.
mencoder mf://#${LIST} -mf type=jpg:fps=${FPS} ...
The video format/codec doesn't really matter, as long as standard tools (mplayer, ffmpeg, vlc, ...) can handle it.
Any ides or suggestions?
Thanks in advance!
One obvious way which should work (at least according to my first tests) is to just write the new jpeg image to the end of the video file - so the video is a mjpeg stream.
cat ${PIC} >> ${VIDEO}
This is an answer to my question, however i was looking for something consuming less space than the pictures stored each by its own would take up.
Other hints?
