使用 AudioRecorder 设置音频格式

发布于 2024-12-11 09:56:04 字数 549 浏览 0 评论 0原文

我正在运行 Android SDK 2.2 并将 Samsung Galaxy Tab 设置为目标，使用以下代码创建录音机对象，

private static final int AUDIO_BUFFER_SAMPLEREAD_SIZE = 8000;
public int channelConfiguration = AudioFormat.CHANNEL_CONFIGURATION_MONO; 
public int audioEncoding = AudioFormat.ENCODING_PCM_8BIT;

创建录音机对象，

bufferbytesize=AudioRecord.getMinBufferSize(samplingRate,channelConfiguration,audioEncoding);

但我总是得到 bufferbytesize 为 -2，这意味着输入格式有问题，我已提供，这是否意味着，Android 模拟器不支持 8 位 PCM 数据的 8000 采样率，或者是否有任何解决方法可以摆脱它，

I am Running Android SDK, 2.2 and set Samsung Galaxy Tab as target, using following code to create Audio Recorder Object,

private static final int AUDIO_BUFFER_SAMPLEREAD_SIZE = 8000;
public int channelConfiguration = AudioFormat.CHANNEL_CONFIGURATION_MONO; 
public int audioEncoding = AudioFormat.ENCODING_PCM_8BIT;

Creating Audio Recorder Object,

bufferbytesize=AudioRecord.getMinBufferSize(samplingRate,channelConfiguration,audioEncoding);

But i am always getting bufferbytesize is -2, which means something wrong with the input format, which i have provided,
Does that mean, on Android Emulator doesn't support 8000 Sampling rate with 8 bit PCM data, or Are there any workaround to get rid out it,
