How To Edit Your Teleconference Recording
If you are putting your teleconference recording onto your website or sending it to clients it needs to sound good. Occasionally you will want to make improvements.
If you are a confident PC user you can do it yourself by following the instructions below.
If you need assistance from HotAir, much as we normally try to do this kind of thing at no charge, it is time consuming so we have to charge $50 per recording. If you need us to help you, call us on

Getting Started
You will need some audio editing software. An excellent free program called Audacity is available at www.Download.com or here
You should also download and install the MP3 plug in.
Removing sections of your conference recording
Open your recording into Audacity
Highlight the area you want to remove by clicking at the start of it and releasing the mouse button at the end of the section. If you press the space bar it will play the section you are about to delete.
Press the DELETE button on your keyboard.
Confirm the correct section has gone and then save the file.
Some people are too loud and others too quiet
HotAir's teleconferencing system will try to make all lines the same volume. However if a line is really quiet the system will not be able to increase it's volume without impairing the sound quality of the other lines.
There are things you can do to improve things using a software plug-in called a compressor. This reduces the loud sound to the same volume as the quiet sounds, hence the name.
Before you do anything with your recording make a back up copy.
Getting started
Open your teleconference recording in Audacity.
Set the vertical scale to DB as shown by the two images below
Looking at our demonstration recording (shown below) you will see the difference in volume of the people in the meeting. You can see that the loud person is at around -15db but the quiet person is at -28 db.
Select all of your recording by clicking on it and the pressing Ctrl A
On the menu bar at the top, select effects and in the drop down menu, compressor. You will see a window similar to below
To make the volume the same we will reduce the volume of the loud person. We know the quiet person's volume is around -28db, so set the Threshold to -28db.
We also need to set how much we will reduce the volume. In this example a ratio of 9:1 worked well.
Click on OK to hear the new version of your recording.
If it sound good, save it. If you think you can do better press Ctrl Z to have another go.
Every recording is different so you will need to experiment with the settings.
