I'm working with a video file supplied by my client. It's from a screen capture program (which shall remain nameless for the present).
It has very terrible audio. The program, which is still remaining nameless, unfortunately compresses the video and audio to the extreme. The audio sounds swishy -- and slightly flanged at times -- as if you're listening to it through a cardboard tube... it's really bad. I've been searching online for a solution to this for a long time. It seems the nameless program manages it's own compression settings and there is no override.
Now the client just sent me an update to a section of the video, and the audio is markedly better. But, in order to make the new audio match the existing audio I have to somehow find an audio equalization setting that matches the frequencies present in the original track.
I can do it by ear, but is there a program or a plugin that can tell me, or show me visually what frequencies are present in an audio sample, so I can tune the EQ settings to match?
