Time Stretching speech & audio signals Description
Time stretching technology is used for time scale modification (changing the speed or duration) of an audio signal without affecting its pitch. The algorithm can be implemented both in frequency-domain (FD) using a Fourier transformation, and in time-domain (TD) using Synchronized Overlap-Add (SOLA) technology. The time-domain modification was chosen for implementation, due to a number of factors: ■ time domain algorithm is easier to implement; ■ it offers better transformation quality; ■ it can be optimized to increase transformation speed; ■ the code is easily converted from float point code to any DSP, ARM or RISC platform. The principle of functioning our algorithm is based on time-domain modification using SOLA technology, such as Waveform Synchronized Overlap-Add (WSOLA). With Time Stretching speech & audio signals you can easily modify the speed and duration of audio files, avoiding pitch alteration in the same time. Time stretching technology can be effectively used: ■ With audio players for changing the duration of music or speech; ■ With audio-video recorder devices or video post synchronization; ■ For voice messanging services (voice mail); ■ For reduce the rate of bit transmission (jitter control) in devices of IP telephony.
