[0015] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below. Obviously, what is described below is only one embodiment of the present invention. For ordinary technicians in this field, other embodiments can be obtained based on this embodiment without paying creative work, and they all belong to the protection scope of the present invention.

[0016] A debugging method for an audio processor, which connects the output end of an audio signal generator to the input end of an audio processor through a high-quality audio cable, connects the input end of an audio analyzer to the output end of the audio processor, and is used to monitor and analyze the signal quality output by the audio processor in real time. An oscilloscope is connected to key nodes to observe the waveform and electrical signal characteristics of the audio signal, initializes all connected devices, and sets appropriate parameters according to debugging requirements.

[0017] Use the audio signal generator to send a series of standard test signals to the audio processor. Here, set the signal type to sine wave, the frequency range from 20Hz to 20kHz, and the amplitude to gradually adjust from low to high. Initialize the audio analyzer, set the sampling frequency to 96kHz, the resolution to 24 bits, and select a comprehensive audio analysis mode, including frequency response analysis, harmonic distortion analysis, signal-to-noise ratio analysis, etc. Set basic parameters for the audio processor, but keep the default parameters.

[0018] Starting from 20Hz, send a sine wave test signal every 100Hz, and gradually increase the frequency until 20kHz. For each frequency signal, record the input and output parameters of the audio processor, including the signal's frequency, amplitude, phase, and the processed frequency response, harmonic distortion and other data.

[0019] Use an audio analyzer to analyze the output quality of each test signal in detail, calculate the signal-to-noise ratio, use an oscilloscope to observe the waveform changes of the signal, form an initial audio parameter model, and draw frequency response curves and distortion curves to intuitively understand the performance characteristics of the audio processor.

[0020] According to the quality characteristics of the output signal, conduct a preliminary analysis and troubleshooting of the internal parameters of the audio processor, analyze the frequency response curve and signal-to-noise ratio, check the noise reduction parameter settings, and identify modules or parameter settings that may have problems.

[0021] Measure the acoustic space characteristics of the environment, use an acoustic analyzer to measure the reverberation time, sound reflection, etc. of the room, adjust the parameters of the audio processor according to the measurement results, adjust the delay parameters according to the size of the room and the speed of sound propagation, set an appropriate delay time, ensure the phase consistency of the sound, increase the threshold of the noise reduction parameters, and avoid excessive noise reduction affecting the authenticity of the audio. At the same time, check the electromagnetic environment and use an electromagnetic interference detector to detect whether there is an electromagnetic interference source. If electromagnetic interference is found, take electromagnetic shielding measures, such as using shielded cables, installing electromagnetic shielding covers, etc., and adjust the anti-interference parameters of the audio processor to improve its anti-interference ability.

[0022] Conduct recording tests under actual operating conditions. During the recording process, monitor the output effect of the audio processor in real time, dynamically adjust the parameters, and use automated debugging tools to automatically adjust the parameters of the audio processor based on real-time collected audio data and preset optimization algorithms. For example, automatically adjust the compressor parameters according to the dynamic range of the audio signal to ensure the dynamic balance of the audio signal, and automatically adjust the noise reduction parameters according to changes in environmental noise to maintain the clarity of the recording.

[0023] After completing the dynamic debugging, a long-term stability test is carried out. The audio processor is run continuously for 30 hours. During this period, various types of audio signals are continuously input, including continuous music playback, intermittent voice recording, etc., to monitor whether the performance indicators of the audio processor remain stable and check whether overheating occurs.

[0024] Perform comprehensive verification tests on the debugged audio processor, perform compatibility tests with other recording devices (such as microphones, audio interfaces, speakers, etc.) to ensure that there are no compatibility issues during connection and use, and perform performance tests under different workloads, such as recording multiple audio channels at the same time, processing audio signals with high dynamic range, etc., to check whether the audio processor can work stably and maintain good audio quality. According to the results of stability testing and verification, perform final optimization and adjustments on the debugging of the audio processor. If problems are found, repair and improve them in a timely manner to ensure that the audio processor can work stably and long-term in the recording studio environment.

[0025] The design of the present invention can be customized for debugging and optimization according to different audio processor models, application scenarios and user needs. Through scientific and reasonable debugging steps and methods, it can give full play to the performance potential of the audio processor, improve audio quality, and provide users with a better audio experience. It has wide applicability and flexibility.
