核心代码只有约1K行Golang代码的音频处理库：Beep

Beep是一个处理和访问音频的库。

特性

• Decode and play WAV, MP3, OGG, and FLAC.
• Encode and save WAV.
• Very simple API. Limiting the support to stereo (two channel) audio made it possible to simplify the architecture and the API.
• Rich library of compositors and effects. Loop, pause/resume, change volume, mix, sequence, change playback speed, and more.
• Easily create new effects. With the Streamer interface, creating new effects is very easy.
• Generate completely own artificial sounds. Again, the Streamer interface enables easy sound generation.
• Very small codebase. The core is just ~1K LOC.

代码样例

package main

import (
    "log"
    "os"

    "github.com/faiface/beep"
)

func main() {
    f, err := os.Open("Rockafeller Skank.mp3")
    if err != nil {
        log.Fatal(err)
    }
}
