Embodiment 1
[0031] According to an embodiment of the present invention, an embodiment of a method for enhancing an audio signal is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.
[0032] figure 1 It is a flowchart of an audio signal enhancement method according to an embodiment of the present invention. Such as figure 1 As shown, the method includes the following steps:
[0033] Step S102, acquiring the current playback volume parameter of the original audio signal.
[0034] In the technical solution provided by the above step S102 of the present invention, the original audio signal can be the input audio signal X in (t), obtaining the current playback volume parameter of th...

[0068] The technical solutions of the embodiments of the present invention are illustrated below in combination with preferred implementation modes.
[0069] With the convenience and miniaturization of multimedia devices, the size of speakers for reproducing audio signals is also reduced, but this will lead to a decrease in the power of the speakers and insufficient reproduction of low-frequency dives. The way to increase the low frequency of small speakers can be by increasing the low frequency EQ. However, although this method can improve the low-frequency hearing of the speaker to a certain extent, the range that can be improved is still very limited, and in the case of a large signal, the reproduced low-frequency signal is also easily distorted, and it is easy to damage the speaker. irreversible damage to the structure.
[0070] Another way to improve the sense of hearing of bass is to use the principle of "virtual bass" in psychoacoustics, which can enhance the virtual b...
Embodiment 3
[0100] The embodiment of the present invention also provides an audio signal enhancement device. It should be noted that the apparatus for enhancing an audio signal in this embodiment may be used to implement the method for enhancing an audio signal in the embodiment of the present invention.
[0101] Figure 6 is a schematic diagram of an audio signal enhancement device according to an embodiment of the present invention. Such as Figure 6 As shown, the audio signal enhancement device 60 may include: a first acquisition unit 61 , a filter unit 62 , a second acquisition unit 63 and a virtual bass enhancement unit 64 .
[0102] The first acquiring unit 61 is configured to acquire the current playback volume parameter of the original audio signal.
[0103] The filtering unit 62 is configured to filter the original audio signal through an equal-loudness filter to obtain a first audio signal, wherein the first audio signal is an audio signal with enhanced sound range.
