Does it make sense to convert the file to a higher audio bitrate?
When a certain file (mp4, flv, etc.) has an audio bitrate of 95kbps, does it make sense to generate a higher bitrate when converting to mp3 or other format (lossy or not)?
Will this result in higher quality audio or just a larger file?
Edits after many answers + comments:
I am not saying that the output is of better quality than the input: obviously this is not possible. (Except to go from a lossless format to the original waveform). I’m talking about whether an output with a higher bit rate than an input will have better quality than otherwise.
Please note that I know that converting between lossy formats is not recommended. Only in some cases the original cd / wave may not be available. The question is just the usefulness of the optional increase in bitrate during conversion.
Perhaps a sub-question is useful: Does the answer depend on the output file type (lossless or lossy)?
the two most popular polls below (this one and this one) seem to speak differently, that is, the bitrates are later said to be not directly comparable, and if the original audio is in a more efficient format, then the audio Output (less efficient) should have a slightly higher bitrate (same idea here and here), but although mp3 is less efficient, I’m not sure which formats are more efficient. (Is it aac?) (- And, in general, the answers seem to fall into one of the two positions represented by the answers with the most votes).
The reality is that if you have a file with a bit rate, it will NOT improve if we increase the bit rate.
If the ORIGINAL encoding has a better bit rate, then it will sound better. But modifying it after encoding it has no effect.
