pcm-player's Issues

可以添加一个从头播放的方法吗?

现在pcm数据全部播放一遍之后,就不能从头播放了,组件内部能否保存接收到的pcm数据,以便支持从头播放,就像 html 的 audio 标签那样

同时添加一个player.replay()的方法

调用destroy方法会报错

bindAudioContextEvent() {
    ...
        self.audioCtx && self.option.onstatechange(this, event, self.audioCtx.state)  // 感觉这里可以加一个判断,不然destroy方法中close的回调触发时self.audioCtx已经被设置为null了
    ...
}

播放不连续呢?

tts返回的数据是以整句的模式返回的,在一整段中,会先后返回多个句子的PCM。我按照返回的顺序,将每一句PCM通过player.feed()进行播放。但是句与句之间播放不连续,时间间隔较长。这个怎么解决呢?

Add download method for PCMPlayer class

Would it be possible to add a .download() method on PCMPlayer? Since it's raw PCM data, I'd like to download a .wav or .pcm file that is ready to be read with VLC or another media player directly. I thought since you already added the corresponding Header for the web version to work, can you implement the .download() method or guide me a little so i can do it myself (I don't have knowledge on audio data i might do wrong things). Thanks

typescript类型定义问题

后面两个参数的类型定义写错了吧?eslint会报错,应该改为这样?

onstatechange: (node: AudioContext, event: Event, type: AudioContextState) => void
onended: (node: AudioBufferSourceNode, event: Event) => void

另外这两个参数可以改为可选吗?

why the player is distorting the audio?

I recorded some audio from retroarch but every audio I play using this lib, the audio gets distorted.
The speed of audio is OK, and yet is a recognizable audio, but the sound gets distorted.
I have run the commands below (you may test in your own env just replacing the retroarch command by any software that emits sound):

# create audio sink to redirect emulator sound
pactl load-module module-null-sink sink_name=RetroArch format=u8 channels=1 rate=44100 sink_properties=device.description="RetroArch_Virtual_Sink"

# run emulator redirecting sound to the new sink
PULSE_SINK=RetroArch retroarch -L /home/unknown/snap/retroarch/957/.config/retroarch/cores/stella_libretro.so /home/unknown/Downloads/Atari\ 2600/Frogger.bin

# start recording the audio from the sink
parec -d RetroArch.monitor --raw --channels=1 --rate=44100 --format=u8 --latency-msec=100 -v > /tmp/output.raw

# after you captured the sound, you can play it using the command
cat /tmp/output.raw | pacat --raw --channels=1 --rate=44100 --format=u8

The sound is played very well when using pacat, but when I try to load it in the browser using the lib, the audio gets distorted.
Also I tried other formats like s16le, s16be, float32le, float32se, etc... And configured the lib to inputCodec as Int16, Int32, Float32 and the audio yet gets distorted.

Is this a bug or it just needs tweaking the configs?
