Introduction to Audio Debugging

1. Sound Testing & Equalizer Adjustment

• When conducting sound testing, adjust the audio buttons slightly within the frequency range of 20-20KHz (the standard human audible frequency range). Continuously record voice comparisons of the volume at each frequency node to track changes and identify inconsistencies.

• Under rated sound conditions, focus on equalizer debugging. Since different people have distinct preferences for music tone and sound color, tailor the equalizer settings to match individual hobbies. For example, bass lovers may increase low-frequency levels, while vocal enthusiasts can enhance mid-range frequencies for clarity.

2. Key Steps for Microphone Testing

• First, set the corresponding frequency modulation (FM) channel for the microphone. Each channel is uniquely matched to a specific microphone, so ensure the channel setting aligns with the microphone type (wired or wireless) to avoid signal interference.

• Start modulation with a low voice, gradually increase the volume of your voice, and record the microphone’s output at each stage. This helps verify if the microphone can capture sound clearly across different volume levels and detect any distortion or signal dropouts.

3. Bluetooth Connection Debugging

• Connect the audio device to the adjustable Bluetooth mode. Test different music modes (e.g., pop, rock, classical) to check how the device performs under various sound profiles.

• Test the Bluetooth connection in different environments (e.g., indoor, outdoor, areas with wireless interference) to evaluate stability. During testing, check if the microphone output and overall volume are balanced and harmonious, with no lag or audio distortion.
