How to compare two takes in one file instead of two links
Ask Vizard Agent for a loudness-matched A/B in a single file. Two separate links make you judge from memory across a gap, and any level difference between them decides the comparison for you: the louder take wins almost every time, whether or not it is the better one.
What do you type into Vizard Agent?
Ask for the file, not the verdict, and don't say which take you think is better. Vizard Agent can give an opinion too, but the file is what settles it. "Match their levels" is the load-bearing clause: without it, the comparison is mostly a loudness test, the most reliable way to reach the wrong answer.
Here are two takes of the same voiceover. Match their levels and put them in one file so I can hear them back to back.
What does Vizard Agent actually do?
Vizard Agent measures before it joins: integrated loudness on each take, then a gain adjustment so both play at the same perceived level, then both assembled into one file with a clear gap between them. What you hear is the difference in the performance, not in the gain. In the session behind this article it:
- Transcribed and evaluated both voiceover takes.
- Measured the loudness of each, and the noise floor alongside it.
- Built a single, matched A/B file from the two and uploaded it so it could be played in a browser rather than downloaded.
- Compared the takes head to head and reported what differed.
- Read the word-level timings for the chosen take so the edit could be built on it. Those timings drive everything downstream, so switching takes later means redoing the timing map.
When does this not work well?
When the takes are long. A three-minute A/B is six minutes of listening, and you'll have lost the first take by the end, so ask for one representative paragraph instead. It doesn't resolve a difference in the script either. And matched loudness isn't matched tone: a take recorded closer to the microphone sounds fuller at the same level.
Common questions
Does it tell me which is better? Vizard Agent will if you ask. The file exists so that you decide first, unprompted.
Does it measure noise too? Yes. Vizard Agent reports the noise floor, and sometimes that decides it.
Can it splice the best lines from both? Yes, from the word timings, once you say which lines.
