Audio output method and device

Abstract

The invention discloses an audio output method and device. The audio output method includes: determining a masking effect curve of frequency domain noise signals, performing perceptual weighting on energy information of source audio signals to acquire energy information after weighting, performing time domain to frequency domain conversion on the source audio signals to acquire frequency domain source audio signals, determining that the energy information after weighting is energy information corresponding to the frequency domain source audio signals, enhancing or weakening the frequency domain source audio signals according to the masking effect curve and the energy information corresponding to the frequency domain source audio signals, performing frequency domain to time domain conversion on the frequency domain source audio signals after being enhanced or weakened to acquire source audio signals after processing, reversely weighting the source audio signals after processing, and outputting audio signals. By combining and analyzing masking effect and an audio weighting mode, interference resistance of audio output equipment is improved without excessively changing output audio energy.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an audio output method and device. Background technique [0002] With the rapid development of terminal technology, more and more portable devices appear on the market, from mobile devices with gradually powerful functions, to popular tablet devices, and wearable devices with great development potential. The common feature of these devices is to provide users with application experience anytime and anywhere, and users can enjoy various services such as network and multimedia in any scene. However, under the application requirements of such devices, there is a big problem: in most outdoor environments, such as buses, subways, shopping malls, etc., the audio output provided by portable devices is often interfered by huge background noise, So that it is impossible to hear the content of the audio output clearly. There are several solutions to this problem: [000...

However, under the application requirements of such devices, there is a big problem: in most outdoor environments, such as buses, subways, shopping malls, etc., the audio output provided by portable devices is often interfered by huge background noise, So that it is impossible to hear the content of the audio output at all

[0006] For the second and third methods mentioned above, although they have the advantages of avoiding the discomfort caused by fully enclosed earphones and using the anti-phase signal of background noise to remove the interference of background noise in the mixed audio, these two methods There are some shortcomings, that is, when the noise signal is removed, it is likely to have a relatively large impact on the normal output audio signal, thus affecting the audio signal effect heard by the user
