Based on the hardware architecture of the audio playing device based on the digital audio signal processing technology, the embodiment of the sound effect adjusting method is provided.
Referring to fig. 2, in a first embodiment, the sound effect adjusting method includes the steps of:
step S10, determining an applied sound effect corresponding to the audio file to be processed according to the audio characteristics of the audio file to be processed;
in this embodiment, before the audio file to be processed is played, the characteristics of the audio are analyzed and identified through the intelligent sound effect analysis module, so that the applied sound effect in the audio file to be processed is determined according to the audio characteristics.
Optionally, the audio features may include frequency domain features, and the frequency domain features may include a spectrum centroid, which is a frequency domain feature and may represent an energy concentration point in a signal spectrum, and a quantized value that can describe a tone color of the signal, that is, a tone color brightness, is determined by performing spectrum analysis on the feature of the spectrum centroid. The timbre brightness is mainly used for judging the sense of volume and the sense of brightness of medium-high frequency and high-frequency signals, and can directly influence the auditory sense of human ears to generate the perception difference of 'timbre brightness/darkness'. In general, the more prominent the high frequency, the brighter the timbre we will perceive, but this does not mean that the timbre is "brighter as better". Once the tone color is too bright, it means that the high frequency is too much, the three frequencies are unbalanced, and at this time, the human ear hearing sense actually has the bad feeling of being hard and sharp, even if some high frequency bands have nonlinear peak bulges, the human ear hearing sense still feels harsh. Therefore, after determining the timbre brightness of the audio to be processed, it is necessary to determine whether the timbre brightness is within a preset appropriate preset range. In some embodiments, a brightness range is preset, when the brightness of the tone color is within the brightness range, it is determined that the sound in the audio file to be processed does not make people feel harsh, and the step of determining the applied sound effect corresponding to the audio file to be processed is performed; otherwise, adjusting the tone brightness to be within the brightness range by signal processing and the like, and then executing the subsequent steps.
Alternatively, the audio features may include a fundamental frequency and an overtone frequency. The fundamental frequency and the overtone frequency are musical features, and the degree of deviation (i.e., the degree of distortion) between the fundamental frequency and the overtone frequency reflects the degree of deviation between the overtone frequency and the integer multiple of the fundamental frequency, and the degree of distortion is defined as the square root of the ratio of the fundamental frequency to the overtone frequency. In some sound effects, the distortion degree in the audio frequency can be increased to achieve the effect of improving the audibility, for example, simulating the power amplification sound effect of a vacuum tube. However, when the audio file to be recorded is to be reproduced with original taste as much as possible, the audio distortion added to the sound effect is no longer necessary. Therefore, the sound effect to which it has been applied is judged by determining the degree of deviation of the fundamental tone frequency and the overtone frequency. In some embodiments, when the deviation degree is greater than the preset first threshold, it is determined that the distortion in the audio is too large at this time, which may cause a negative hearing sensation, and the deviation degree is adjusted to be less than or equal to the preset first threshold. In other embodiments, when the deviation degree is greater than a preset second threshold, it is determined that a distortion sound effect exists in the audio file to be processed, where the second threshold is smaller than the first threshold.
Optionally, the audio features may include harmonic features, and the musical instrument category included in the audio file to be processed may be determined through the harmonic features. The harmonic frequencies of different types of instruments are different, for example, the harmonic frequency range of violin is 4k-15k, and the harmonic frequency range of cello is 1k-6.5 k. In some sound effects, the sound effects of some musical instruments can be simulated by changing the harmonic frequency of the audio, so that the range of the harmonic frequency in the audio file is determined to be matched with the preset harmonic frequency range, and the musical instrument type in the audio characteristic is determined according to the frequency range obtained by matching, so that the musical instrument sound effects in the audio file to be processed are judged according to the musical instrument type.
Step S20, determining a sound effect to be applied corresponding to the audio file to be processed;
furthermore, the intelligent sound effect analysis module can also determine the sound effect to be applied corresponding to the audio file to be processed. The to-be-applied sound effect is characterized in that the sound effect which can be added in the to-be-processed audio file is obtained through analysis of the intelligent sound effect analysis module, for example, bass sound effect and reverberation sound effect can be applied in the to-be-processed audio file, and then the bass sound effect and the reverberation sound effect are both used as the to-be-applied sound effect of the to-be-processed audio file. It should be noted that the determination method of the to-be-applied sound effect is also to analyze the to-be-applied sound effect suitable for the processed audio file by extracting the audio features in the processed audio file, and therefore, the determined type of the to-be-applied sound effect may be the same as or different from the type of the applied sound effect.
Optionally, in some embodiments, the intelligent sound effect analysis module may obtain the environmental information based on the setting of the user and a sensor set on the audio playing device, and determine the type and parameters of the sound effect to be applied, for example, the sensor collects the environmental information, and identifies that the user is in an environment in a room, and then obtains that the sound effect to be applied is a reverberation sound effect.
Step S30, determining a target sound effect according to the applied sound effect and the sound effect to be applied;
and step S40, processing the audio file to be processed based on the target sound effect.
After determining the applied sound effect and the to-be-applied sound effect in the to-be-processed audio file, determining a target sound effect of the to-be-processed audio file actually applied in the playing process according to the two sound effects, wherein the target sound effect comprises the applied sound effect added in the to-be-processed audio file in advance and the to-be-applied sound effect determined through the intelligent sound effect analysis module.
Optionally, in order to avoid reducing the hearing sense of the user due to the superposition of the same type of sound effects, the intelligent sound effect analysis module needs to determine the sound effect types of the applied sound effect and the sound effect to be applied, and if the sound effect type of the applied sound effect is different from the sound effect type of the sound effect to be applied, the applied sound effect and the sound effect to be applied are jointly used as the target sound effect; and if the sound effect type of the applied sound effect is the same as the sound effect type of the sound effect to be applied, taking the applied sound effect as the target sound effect. It should be noted that, because the types of the to-be-applied sound effect and the applied sound effect in the audio file may be one or multiple, the obtained target sound effect may be one or multiple, the sound effects included in the target sound effect may be the to-be-applied sound effect or the applied sound effect, or the target sound effect may include a plurality of the to-be-applied sound effects and the applied sound effect at the same time, and the factors depending on the different situations are the differences of the audio characteristics in the different to-be-processed audio files.
In the technical scheme provided by this embodiment, an applied sound effect corresponding to a to-be-processed audio file is determined by analyzing audio features of the to-be-processed audio file, then the to-be-applied sound effect corresponding to the to-be-processed audio file is determined, a target sound effect corresponding to the to-be-processed audio file is determined according to the applied sound effect and the to-be-applied sound effect, and finally the to-be-processed audio file is processed based on the target sound effect. The negative listening feeling of the played audio file due to the superposition of sound effects is avoided, and better audio playing experience is brought to the user.
Referring to fig. 3, in the second embodiment, based on any one of the embodiments, before the step S20, the method includes:
step S50, determining fundamental tone frequency and overtone frequency in the audio file to be processed based on a spectrum analysis algorithm;
the step S20 includes:
step S21, determining the sound effect to be applied of the audio file to be processed according to the fundamental tone frequency and the overtone frequency.
Optionally, the present embodiment provides a method for determining the sound effect to be applied according to the pitch frequency and harmonic frequency of the audio file to be processed. Based on a spectral analysis algorithm, the fundamental (i.e. fundamental) and overtone (i.e. harmonic) frequencies of the audio file to be processed can be determined. The fundamental frequency is a main frequency in an audio signal, which determines the pitch of a sound played by the audio, and the overtone frequency is a high-frequency in the audio signal, which has the effect of beautifying the sound, giving a sense of presence and clarity to the sound. The balance quantity at the low-end frequency of the fundamental tone frequency is properly improved, so that the sound is warmer and richer, and the balance quantity of the fundamental frequency is properly attenuated, so that the sound is wider; and the balance of the overtone frequency is improved, so that the scene feeling and the definition of the sound can be enhanced, and the balance of the overtone frequency is reduced, so that the sound is prevented from being too harsh. Based on the principle, the listening feeling of a user is improved by adjusting the overtone frequency and the fundamental tone frequency of some sound effects, therefore, the intelligent sound effect analysis module matches the sound effect to be applied corresponding to the condition by determining the overtone frequency and the fundamental tone frequency in the audio file to be processed when the overtone frequency and the fundamental tone frequency meet the preset condition.
In the technical scheme provided by this embodiment, the fundamental tone frequency and the overtone frequency in the audio file to be processed are determined through a spectrum analysis algorithm, when the preset conditions are met according to the fundamental tone frequency and the overtone frequency, the audio to be applied corresponding to the preset conditions is determined, whether the audio to be applied exists in the audio file to be processed is automatically identified and adapted, compared with the traditional method that a user selects the audio through own subjective listening sensation, the audio may have a negative effect on the listening sensation, in this embodiment, the audio proper audio of the audio file is automatically matched through audio features, negative listening sensation generated due to the audio superposition phenomenon that the user may appear when selecting the audio is avoided for the played audio file, and better audio playing experience is brought for the user.
Referring to fig. 4, in a third embodiment, based on any one of the above embodiments, before the step S20, the method includes:
step S60, determining tone brightness, musical instrument type and/or sound source position in the audio file to be processed based on a full-connection neural network analysis algorithm;
the step S20 includes:
step S22, determining the sound effect to be applied corresponding to the audio file to be processed according to the tone brightness, the type of the musical instrument and/or the sound source position.
Optionally, the present embodiment provides another method of determining sound effects to be applied. In the embodiment, the tone brightness, the type of the musical instrument and/or the sound source position in the audio file to be processed are determined through a full-connection neural network analysis algorithm. A large number of audio file training sets are input into an algorithm database in advance, and data in the training sets are classified through a fully-connected neural network, so that audio characteristics of several audio files including tone brightness, musical instrument types and sound source positions are obtained. And matching the reference tone color brightness, the reference instrument type and/or the reference sound source position in the preset data set according to the tone color brightness, the instrument type and/or the sound source position, and selecting a sound effect corresponding to the matched reference tone color brightness, the reference instrument type and/or the reference sound source position as a sound effect to be applied.
In the technical scheme provided by this embodiment, the tone brightness, the type of an instrument and/or the position of a sound source in an audio file to be processed are determined through a full-link neural network analysis algorithm, and when the tone brightness, the type of an instrument and/or the position of a sound source meet a preset condition, a sound effect to be applied corresponding to the preset condition is determined. Compare in when traditional user removes the selection audio through the subjective audibility of oneself, the audio probably brings the negative effect to the audibility, through the audio frequency characteristic automatic matching audio file suitable audio in this embodiment, avoided the audio file of broadcast because the user produces negative audibility because the audio superposition phenomenon that probably appears when selecting the audio, bring better audio playback experience for the user.
