Embodiment 1

[0026] Embodiment 1. An audio playback method, the flow chart of which is as follows figure 1 shown, including:

[0027] S1, obtaining the audio type information of the audio to be played;

[0028] In this example, there may be multiple ways to acquire the audio type information, for details, refer to the descriptions of the following embodiments 2 to 4.

[0029] S2. Obtain corresponding equalizer parameters according to the audio type information;

[0030] S3. Load the equalizer parameters and play the audio.

[0031] In this embodiment, the corresponding equalizer parameters are obtained according to the audio type information; loading the equalizer parameters and playing the audio realizes the automatic EQ setting of the audio playback, so that the user does not need to set the EQ corresponding to the audio type by himself. A better playback effect is obtained, and the user's listening experience is improved.

Embodiment 2

[0032] Embodiment 2, an audio playback method, the flow chart is as follows figure 2 shown, including:

[0033] A1, performing spectrum analysis on the audio to be played, and obtaining the frequency domain distribution of the audio to be played;

[0034] In the embodiment of the present invention, carrying out spectrum analysis can be finished by software or hardware calculation, if equipment such as computer, PDA mobile phone based on general structure, can realize by software algorithm, and based on special-purpose audio player, as MP3, CD machine, MD machine and other equipment can be implemented by integrating the spectrum analysis function of the audio decoding chip. The specific implementation can refer to various existing spectrum analysis methods, which will not be described in the present invention.

[0035] There are many specific processes for performing spectrum analysis, such as:

[0036] The frequency domain of the audio to be played is segmented; the sound r...

Embodiment 3

[0045] Embodiment 3, an audio playback method, the flow chart is as follows Figure 5 shown, including:

[0046] B1, performing spectrum analysis on the audio to be played;

[0047] In the embodiment of the present invention, carrying out spectrum analysis can be finished by software or hardware calculation, if equipment such as computer, PDA mobile phone based on general structure, can realize by software algorithm, and based on special-purpose audio player, as MP3, CD machine, MD machine and other devices can be implemented by integrating the spectrum analysis function of the audio decoding chip. For specific implementation methods, reference can be made to various existing spectrum analysis methods, which will not be described in detail in the present invention.

[0048] For the specific spectrum analysis process, reference may be made to the description of step A1 in the first embodiment, which will not be repeated here.

[0049] B2, obtain the corresponding audio type a...

Abstract

The invention discloses an audio playing method and an audio player. In the embodiment of the invention, corresponding equalizer parameter is obtained according to the audio type information; the equalizer parameter is loaded to play the audio. The invention realizes automatic EQ setup of audio playing, and users can obtain better playing effect without setting EQ corresponding to the audio type,thus improving hearing experience of users.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio playing method and an audio playing device. Background technique [0002] As digital multimedia applications enter millions of households, people can play digital audio files on computers, CD players, MP3, MP4, and even mobile phones, and specifically decode audio files through the integrated software or hardware audio player inside the device , and then converted to analog output, common audio file formats include: MP3, WAV, MID, AMR, APE, etc. [0003] The player in the audio playback device is generally provided with an equalizer (Equalizer, EQ), and the function of the equalizer is to adjust the gain value of each frequency band signal. The equalizer can be based on the digital signal processing part or the analog signal processing part. EQ modifies the overtone level of each frequency in the sound to optimize for a certain type of audio, enhance people's h...
