A lossless format preserves the processed result but cannot restore quality lost in the source.
Pitch shifting changes notes and register while preserving tempo. Semitone controls help move a song into a comfortable range or create sound effects. Start with a small adjustment and compare against the original: large transpositions can change the perceived timbre.
The tempo multiplier speeds up or slows down the entire recording without a linked pitch change. It is useful for practice, dance and preparing material. A value of 0.8 is slower and 1.2 is faster; the resulting duration changes accordingly.
Echo adds distinct repeats, while reverb creates a sense of space and fading reflections. They are different effects and can be combined in a chain. Moderate settings generally preserve clarity better; listen carefully to phrase endings and pauses.
Normalization targets perceived loudness, while gain changes signal level. Bass and treble controls adjust tonal balance. Gains across multiple steps accumulate: listen to the final output and check any warnings about excessive levels.
Combine up to six steps and set their order, such as tempo, equalization, reverb and normalization. The full file is processed rather than a short preview. Compare the source and output, then choose a format for listening or further editing.
Yes. Effects apply to the entire recording. Tempo changes alter its duration; a short preview does not replace the finished file.
