Example 2
Referring to fig. 3-5, the present embodiment provides a sound adjusting method applied in the above system for correcting the pitch sound, including the following steps,
s1: the sound signal input module 100 obtains original sound data, in this step, a singer provides the original data or adjusts audio made by the singer in a hard disk in batch, and in the case of batch audio adjustment, a storage provides the original data.
Specifically, the digital processing of the sound signal includes sampling, quantization and encoding, the sampling refers to a process of converting a time-continuous analog signal into a digital signal, and the amplitude and time of the converted digital signal are discrete. The sampling process comprises two important physical quantities, namely a sampling period and a sampling frequency, wherein the sampling period is each sampling time interval, and the reciprocal of the sampling period is the sampling frequency. The higher the sampling frequency is, the more data are obtained in unit time, the better fidelity effect can be achieved, and in order to ensure the sound sampling quality and avoid distortion, the sampling frequency at least reaches twice of the highest frequency of the sound signal. The sound signal quantization means that each sample of the sampling is represented by a discrete value, and the process is also called analog-to-digital conversion, and the samples are represented in a binary number mode after being quantized, wherein the number of the binary number is quantization precision. It is clear that the higher the accuracy with which the quantization is performed, the higher the quality of the sound, but the larger the required storage space. In this embodiment, the image of the original sound signal after sampling and quantization can be referred to the schematic diagram of fig. 5.
Furthermore, the audio signal is already represented in a digital form after being quantized, but needs to be encoded and compressed according to a certain rule for convenience of transmission, processing and storage. The sound signal is encoded to obtain digital audio. The amount of sound information increases and the space for storage increases, and assuming that analog sound is digitized, in bytes and not compressed, the storage amount can be calculated by the following formula:
the storage amount is the sampling frequency × the number of quantization bits/8 × the number of channels × time.
For example, the sampling frequency is 44.1KHz, 1s stereo sound is recorded by using 16-bit quantization bits, and the storage space required for generating the waveform is 44100 × 16/8 × 2 × 1 or 176400 bytes. Therefore, the problem of storage space is also considered during sound processing, and the integrity of sound processing information storage is ensured.
The tone is mainly related to the frequency of the waveform, and the frequency of the sound wave is high, so the tone is also high; the loudness is related to the amplitude of waveform vibration, and the loudness is larger when the vibration amplitude is larger; timbre is the characteristic of a person that distinguishes two sounds having the same loudness and the same pitch from each other, and is related to the shape of the vibration waveform of a sound wave or the spectral structure of the sound. Therefore, the waveform signal generated by the sound can encode and interpret the signals of the original loudness, the original tone and the original tone of the original sound, and finally obtain the digital signal of the digital audio.
S2: the input module 202 receives the original sound data for pre-adjustment, where the pre-adjustment includes applying a digital signal processing algorithm to make the sound softer, more magnetic, and without noise, and the digital signal processing technology is a technology for converting analog information (such as the sound of this embodiment) into digital information. Generally referred to as a chip or processor that performs these functions, or they may also be used to process this information and output it as an analog electrical signal, obviously a pre-conditioning of a digital signal in this embodiment. Therefore, this step includes a process of performing noise reduction processing on the sound signal.
S3: the sound adjusting module 201 combines the adjusting reference module 204 and the intelligent voice matching module 205 to position, match and adjust the pre-adjusted sound data into the adjusted sound data. In this step, the sound adjusting module 201 adjusts one or more of the original loudness, the original pitch, and the original timbre in the original sound data to the standard loudness, the standard pitch, and the standard timbre corresponding thereto, and the sound adjusting module 201 performs positioning according to the one-to-one correspondence between the original time parameter and the standard time parameter. For example, in a song, the original loudness corresponds to the standard loudness, the original pitch corresponds to the standard pitch, and the original timbre corresponds to the standard timbre for the same time parameter of the original sound data and the standard sound data. The adjustment reference module 204 stores standard voice data in advance, and calls the standard voice data when necessary.
The intelligent voice matching module 205 analyzes the voice content in the original voice data and the standard voice data, performs intelligent matching, and locates the adjustment of the original loudness, the original tone, and the original tone in the original voice data according to the matching result. The intelligent voice matching module 205 and the sound adjusting module 201 are positioned in two independent positioning modes, which can be selected by a user, i.e. the matching positioning can be performed according to time parameters or the matching positioning can be performed according to lyrics.
In the embodiment where the time-positioning is, for example, 2 minutes and 06 seconds (positioning) of the song, the original vocal sound is so (reference standard data), and the vocal sound sung by the singer is mi (original data), the system adjusts mi sung by the singer to so at the time node of 2 minutes and 06 seconds.

Example 3
Because the distance between the microphone and the sound source affects the recording performance of the input sound signal input module 100 during the actual sound recording or singing process, when a user inputs a fixed volume value at a client, the actually output volume value is not stably output at the fixed volume value but continuously changes along with the difference of the distance position of the microphone, and the problem that the volume value of the subsequently tracked output sound is large in time is caused, so that the sound adjustment effect is greatly affected. In the prior art, the volume of subsequent output is adjusted according to the fed back volume after the actual output of the sound, and the mode has a certain delay defect due to the fact that the feedback is needed, so that the synchronization of the volume output at the same time cannot be ensured.
Referring to the illustration of fig. 7, therefore, the present embodiment also considers the problem that the distance between the sound source and the microphone cannot be stabilized with respect to the actual output volume, and proposes a self-adaptive volume adjustment method based on the sound adjustment module 201. Compared with distance detection, the distance is the root cause of volume difference, different distances need to be calculated and matched with corresponding volumes, corresponding volumes are output after the actual distance is identified, and sounds emitted by different users are definitely different under the same distance, so that the volume emitted by a sound source under the distance cannot be ensured at all, and the adjustment precision is influenced.
Further, in this embodiment, the sound adjusting module 201 specifically further includes the following adjusting steps:
the sound detection module 201a detects an actual volume value of a sound source;
the user inputs a preset volume threshold value into the feedback processing module 201b through the provided interactive interface;
the actual volume value is input into the feedback processing module 201b and is subjected to difference calculation with a built-in preset volume threshold;
inputting the calculated difference value into the compensation suppression module 201c for difference compensation and then outputting a compensation volume value;
the actual volume value and the compensation volume value are synchronously superposed to be used as a common output value;
the common output value is used as a final volume control value of the sound adjusting module 201 to control and adjust the actual volume of the original sound after being output.
In this embodiment, the sound volume is also called loudness and intensity, and refers to subjective feeling of the human ear on the intensity of the heard sound, and the objective evaluation scale is the amplitude of the sound, and the feeling is derived from the pressure generated when the object vibrates, i.e., the sound pressure. The object vibrates through different media, conducting its vibrational energy away. In order to quantify the perception of sound as a monitorable indicator, one divides the sound pressure into "levels" -sound pressure levels, so as to objectively represent the intensity of the sound, which is called "decibels" (dB).
Further, the sound detection module 201a is disposed at the front end of a microphone circuit of the microphone, and an output of the sound detection module 201a is connected to an input of the microphone, wherein the sound detection module 201a includes a microphone, an amplifier, an attenuator, a weighting network, a detector and an indicator, and the sound detection module converts an ambient sound into an electrical signal by matching a pre-amplifier transformation impedance with an output impedance of the microphone, and finally inputs the electrical signal to the effective value detector to output a sound level value. More specifically, in this embodiment, a variable resistor is used as a load to perform impedance matching, and the relationship between the load size and the maximum peak value of the output voltage of the microphone and the saturation current is as follows:
RL＝umax/IDSSin the formula umaxIs the maximum peak value of the output voltage of the microphone, IDSSFor saturation current, typically 480 μ A, the maximum peak microphone output voltage is calculated to determine the load size.
Defining the ratio of the microphone output voltage U to the input sound pressure P: s is U/P;
according to the relation between the sound pressure P and the sound pressure level L: l ═ 20lg (P/P)0) Where P is the root mean square sound pressure, P0As reference sound pressure (2X 10)-5Pa), the effective value of the microphone output voltage is known as: u ═ S × p0×10L/20So the maximum peak value of the microphone output voltage:
Umax＝K1×S×p0×10Lmax/20in the formula K1Is the peak factor, L, of the output voltage signal of the microphonemaxIs the maximum sound pressure level of the microphone input.
Referring to the schematic of the microphone impedance matching circuit of fig. 6, the load size is determined to be 19.8k Ω according to the above-described impedance matching circuit of the finally determined satisfactory sensor, and the output characteristic of the microphone is: voltage range: -9.5V to +9.5V, and the minimum value of the voltage change is 0.366 μ V.
The sound is converted into electric signal by microphone, the output signal of microphone is passed through amplifier (formed from operational amplifier LM386, and can be used for amplifying trace quantity of A.C. voltage signal, at the same time can be used for full-wave rectification of A.C. signal), so that the amplitude-frequency characteristics of the output voltage signal can meet the measurement requirements, the microphone is an energy conversion device for converting sound wave signal into electric signal, firstly, the amplifier can be used for adding output signal into weighting network, and can be used for making external filter for signal, then the signal can be amplified to a certain amplitude value by means of attenuator and amplifier, and can be fed into effective value detector for detection, and finally the indication head can give out display for.
In this embodiment, the detector converts the ac signal into a dc signal, and sends the dc signal to the indicator to display the measurement result, and the converted dc signal may correspond to the average value, peak value or effective value (RMS) of the ac signal, so there is an average value, peak value or effective value detector. The method comprises the steps of A/D conversion, square, time weighting, logarithmic conversion and display or output, wherein the time weighting is exponential average of a time constant specified for the square of instantaneous sound pressure, a digital signal processor converts a sound pressure signal into a corresponding decibel value and outputs the decibel value, and the conversion relation is as follows: xdB＝10lg(P/p0) Wherein X isdBIs the actual displayed decibel value.
Further, the embodiment defines a preset volume threshold SdBFor the target volume value set by the user through the software interface, since the distance of the sound source causes the deviation between the actually output volume and the target volume, the decibel value (actual volume value) output by the sound detection module 201a is input into the feedback processing module 201b for difference calculation: ddB＝SdB－XdB. Compensating for rejection based on the resulting difference inputThe internal rotation of the module 201c into the output voltage U is compensated or suppressed, which is a reverse derivative process according to ddB＝10lg(P/p0) The actual sound pressure P is calculated, and the ratio S of the output voltage U to the input sound pressure P defined above, i.e., S ═ U/P, is converted into U ═ S · P, and the value of the output voltage U actually compensated or suppressed is known. Converting the voltage value to be compensated into the required human output voltage to be compensated by the driving power supply according to the calculated output voltage U value, outputting the voltage to the sound detection module 201a by using the D/A conversion interface, inputting the compensated or suppressed decibel value to the feedback processing module 201b again for secondary difference calculation, and when D is the calculated output voltage U valuedBWhen the sound signal is less than 0.1, the input sound adjusting module 201 adjusts the sound, and finally the sound signal is output by the sound signal output module 300. It is understood that the suppression of the voltage is implemented by using a synchronous voltage suppressor and a voltage compensator, for example, as compared with the driving power supply provided with a suppression capacitor. And when the calculated difference is a positive number, turning on the voltage device for discharging, and when the difference is a negative number, turning on the voltage device for charging, and finally realizing compensation and inhibition, which is not described in detail.
In this embodiment, to verify the adjustment accuracy of the method, the error of the actually output volume value with respect to the preset value is detected at different distances, the sound source position is given, and the microphone 1 which is not equipped with the method, the microphone 2 which is used for traditional distance detection and the microphone 3 which is used for sound source detection are respectively placed at positions 10mm, 20mm, 40mm, 60mm and 90mm away from the sound source position, in the test, the sound source is selected to be the audio frequency with the stepwise fluctuation of the volume, when the above 5 detection positions are detected, the volume of the corresponding sound source is 10dB, 20dB, 30dB, 40dB and 50dB, the preset microphone output volume is 30dB, the sound volume output by the three microphones is detected in real time by using the sound decibel detector at the sound production positions at the above different distances, the actual test result is as shown in fig. 8-9, as can be known from fig. 8, the microphone 1 has no compensation and inhibition effects, the volume level of the actual output is set to correspond to the volume emission level of the sound source of 10dB, 20dB, 30dB, 40dB and 50dB, and the volume level of the actual output is decreased as the distance increases. The microphone 2 has an adjusting function, and when the position is far and the sound is large, the actual output effect is obviously lower than that of the microphone 3, namely the adaptive adjusting method provided by the embodiment. The error of fig. 8 shows that the error of the method can be stabilized between 0 and 0.2 with the increase of the distance, and the output error of the microphone 2 is as high as 2 with the increase of the distance by using the distance detection, and the output precision is obviously lower than that of the method, so that the adjusting method provided by the embodiment has obvious advantages compared with the traditional detection distance adjusting method.
