Luckfox Pico Plus + MIC 咪头无法录制声音
Posted: 2024-03-24 5:11
我在plus的TP5: MIC1P、TP6: MIC0P分别连接了咪头的黑线负极和红线正极，如下图，
并使用文档的命令进行测试，即

我只想完成麦克风的录制功能？请问是哪里出问题了吗？
日志如下：rk_mpi_ai_test --sound_card_name=hw:0,0 --device_rate=16000 --device_ch=2 --out_rate=16000 --out_ch=2 --output=/tmp
对于保存的pcm文件，我使用Audacity软件进行试听；此外，我使用以下脚本将pcm转换为wav文件，# rk_mpi_ai_test --sound_card_name=hw:0,0 --device_rate=16000 --device_ch=2 --out_rate=16000 --out_ch=2 --output=/tmp

但无论是pcm文件，还是wav文件，我播放后，都只听到10秒刺耳的蜂鸣声（不像是录制的声音）。def pcm_to_wav(pcm_path, wav_path=None, channels=1, bits=16, sample_rate=16000):
if wav_path is None:
wav_path = os.path.splitext(pcm_path)[0] + ".wav"
pcmf = open(pcm_path, 'rb')
pcmdata = pcmf.read()
pcmf.close()
if bits % 8 != 0:
raise ValueError("bits % 8 must == 0. now bits:" + str(bits))
wavfile = wave.open(wav_path, 'wb')
wavfile.setnchannels(channels)
wavfile.setsampwidth(bits // 8)
wavfile.setframerate(sample_rate)
wavfile.writeframes(pcmdata)
wavfile.close()
print(f"converted .pcm to .wav successfully, and saved into {wav_path}.")
