Question

Is it possible to increase the bit rate of an audio file, yet end up with lower-quality audio than the original? Select 1 or more than 1 response*" Yes, if the selected bit depth is large but the sample rate is too small. Yes, if the selected sample rate is large but the bit depth is too small Yes, this will happen virtually every time if both the sample rate and the bit depth are larger than what was in the original audio file No. Yes, this will happen virtually every time if both the sample rate and the bit depth are smaller than what was in the original audio file.

Explanation / Answer

The answer is Yes, we definitely have chances to increase the bit rate of an audio, yet end up with lower-quality audio than the Original

1. Generally, if the sample rate is too small , we have too many samples available.

In this case, if bit depth is large we end up with lower quality audio than the original

However, if the bit depth is also small, we never need to loose the quality

2. If the sample rate is too large, ultimately we end up with lower quality audio than the original because there are only few samples available less than the needed samples.

So, we can choose the following options to increase bit rate and end up with lower quality audio than the original,

Selected Option 1 : Yes, if the selected bit depth is large but the sample rate is too small

Selected Option 2 : Yes, if the selected sample rate is large but bit depth is too small
