Abstract
A method and an apparatus for determining an inter-channel time difference parameter are provided, so that precision of a determined ITD parameter can adapt to channel quality. The method includes: determining a target search complexity from plurality of search complexities, where the plurality of search complexities are in a one-to-one correspondence with plurality of channel quality values; and performing search processing on a signal on a first sound channel and a signal on a second sound channel according to the target search complexity so as to determine a first inter-channel time difference ITD parameter corresponding to the first sound channel and the second sound channel.
Claims18
A method for determining an inter-channel time difference parameter, the method comprising:
- determining a target search complexity from a plurality of search complexities, wherein the plurality of search complexities are in a one-to-one correspondence with a plurality of channel quality values;
- and
- performing search processing on a signal on a first sound channel and a signal on a second sound channel according to the target search complexity so as to determine a first inter-channel time difference (ITD) parameter corresponding to the first sound channel and the second sound channel.
An apparatus for determining an inter-channel time difference parameter, the apparatus comprising:
- a processor;
- and
- a memory storing a program to be executed in the processor, the memory comprising instructions for:
- determining a target search complexity from a plurality of search complexities, wherein the plurality of search complexities are in a one-to-one correspondence with a plurality of channel quality values, and
- performing search processing on a signal on a first sound channel and a signal on a second sound channel according to the target search complexity so as to determine a first inter-channel time difference (ITD) parameter corresponding to the first sound channel and the second sound channel.
