Lower bitrate for smaller delivery files
Voice, speech and preview files can often tolerate a lower bitrate than demanding music content, although the acceptable level depends on the codec and source.
Changes the audio bitrate used for the output. A lower bitrate usually means a smaller file and can reduce audio quality.
Bitrate describes how much encoded data is used over time. MimiFile's bitrate tool re-encodes supported audio at the selected target data rate so you can prepare a smaller delivery file or meet a platform specification. A higher kbps value can preserve more encoded detail, but it also tends to produce a larger file; increasing bitrate on an already-lossy source does not restore information that was previously discarded.
Voice, speech and preview files can often tolerate a lower bitrate than demanding music content, although the acceptable level depends on the codec and source.
Re-encoding a low-bitrate file at a larger kbps value creates a larger representation of the existing signal; it cannot reconstruct detail removed by the earlier encode.
Bitrate measures encoded data per second, while sample rate describes how frequently the audio waveform is sampled. They solve different technical requirements.
kbps means kilobits per second. It is a data-rate measure commonly used to describe compressed audio encoding.
For the same codec and duration, a lower target bitrate generally produces a smaller encoded file, with a possible quality tradeoff.
No. The new file can have a higher encoded bitrate, but information already lost in the 128 kbps source cannot be recreated by re-encoding it at 320 kbps.
