I’ve only been recording since 2001, and when I started I found the usual places on the internet. The more I’ve learned about our human auditory system, the more I’m skeptical of what people say they hear, especially if they claim that a particular microphone or preamp or cable has some magical property. I learned that we humans can easily hear differences that don’t really exist. After all, the performance is by far the most important component of a track, and every aspect of any recording is a matter of taste.īut I do like to know “about stuff.” Back in hifi days I learned about double blind testing. My recording philosophy is pragmatic, skeptical, not super critical.

Be sure to spend a few moments going through the tutorials to better understand the power of Wavosaur and of this terrific free utility. While I was perusing the Wavosaur tutorials I discovered another EQ tool, called PushTec 5.1 and I was startled by the excellent selection of presets.

The Classic series of effects are all free downloads, and no one should be without Classic EQ and Classic Reverb. Some of my favorite VST plugins are created by Kjaerhus Audio.

These are software tools for audio that can be added to any program that knows how to be a VST host, and Wavosaour is just such a program. Wavosaur is a handy audio tool with a simple interface and good performance, but it needs a little help from some other free software tools called VST plugins. Of course it’s a lot easier to follow these steps in a video demonstration, so please check this one out. Now you’re ready to upload your video with its enhanced audio. So set the Audio field to the AAC codec and save the file. We’re almost done, but we need to recompress the audio – it’s currently an uncompressed WAV file and we need to return it to the AAC format (or other as appropriate) that we started with.
Set the source to External WAV and Open the file we just ehanced in Wavosaour. Now merge the enhanced audio file using the Audio : Main Track menu option. Set the container Format to match the file type. Restart Avidemux and open the trimmed clip. (Maximum volume in a digital audio file is called 0dB, so all volume levels are expressed as negative numbers.) Use the Process : Normalize menu option, then select Custom and set the value to -3. In our example we’ll only adjust the volume, and we’ll do that in the simplest way, by normalizing the file to -3dB. Now start Wavosaur and open the newly extracted audio file. Then save the audio from this video using the Audio : Save menu option, being sure to add the. We want to save the audio as an uncompressed WAV file in most cases, so set the Audio codec to PCM. As always with Avidemux we must enter the file extension, and it should match the container format. Avidemux will only save the portion of the video within the A and B markers. Then set the container format to match the original video, and save the file, preferably to a new name, retaining the original. The A and B markers in Avidemux make this an easy task, just be sure to only set these markers on I frames, not P frames.
Next we trim the video to eliminate alternate takes and start and stop activity that we don’t need to display. We start by opening the video in Avidemux. With these two tools we can tweak our camera audio by raising volume, adding reverb, adjusting tone, and so on. Naturally a cheapskate like me is only interested in free solutions, so the software tools for this project are Avidemux for video and Wavosaur for audio. So this post will describe the steps involved in separating the audio from the video, processing the audio, and merging the improved audio stream back to the video. This is a very handy technique, and can give great audio quality in the final video, but sometimes we only have camera sound available.
In my last blog entry I described the process for merging audio and video recorded on two different devices, for instance, replacing the audio in a Flip Mino HD video with audio recorded on a Zoom H2.
