使用 Overtone 从磁盘读取声音文件？

Question

我想使用 Overtone 从磁盘播放更长的连续音频文件。

我知道 Overtone 有 facilities for loading in samples into memory，但鉴于这些文件又长又大（可能以小时为单位），这不是我想要使用的方法。

SuperCollider - Overtone 用作其音频引擎 - 但是，还有另一种加载和流式传输文件的方法，即 using DiskIn, which Overtone also seems to have, but I wasn't able to find (docs, github) 相应的 Buffer.cueSoundFile() 函数。

Overtone 有 cueSoundFile 吗？我可以使用其他方法吗？

Answer 1

cueSoundFile 是等效的 osc 消息 /b_read 的更高级术语，您可以在 Overtone 中找到 overtone.sc.buffer/buffer-cue.

作为一个 5 秒的演示，它播放磁盘中的 2 声道文件。

(demo (disk-in 2 (buffer-cue "~/Music/10mb.wav")))

以及磁盘输入文件 (SC DiskIn)

user=> (doc disk-in)
-------------------------
overtone.live/disk-in
([numChannels bufnum loop])

  stream audio in from disk file

  [numChannels :none, bufnum :none, loop 0]

  numChannels - Number of channels in the incoming
                audio.
  bufnum      - Id of buffer
  loop        - Soundfile will loop if 1 otherwise
                not.

  Continuously play a longer soundfile from disk. This
  requires a buffer to be preloaded with one buffer size of
  sound. If loop is set to 1, the soundfile will loop.
