The present disclosure relates to a method of editing an audio stream (S) having at least one tone (T1) extending over time in said stream. The method comprises cutting the stream at a first time point of the stream, producing a first cut (A) having a left cutting end (AL) and a right cutting end (AR); allocating a respective memory cell to each of the cutting ends; in each of the memory cells, storing information about the tone; and, for one of the cutting ends, concatenating the cutting end with a further stream cutting end which also has an allocated memory cell with information stored therein about any tones extending to said further cutting end. The concatenating comprises using the information stored in the memory cells for adjusting any of the tones extending to the cutting ends.
