byted-las-audio-convert

Converts and transcodes audio file formats and encoding parameters using Volcengine LAS. Audio format conversion between wav, mp3, flac, m4a, ogg, aac and other audio formats. Adjusts sample rate (resample, downsample, upsample), bit rate (bitrate), channels (mono, stereo, channel mixing), audio compression, and audio quality settings via ffmpeg parameters. Supports TOS cloud storage paths and local file upload. Use this skill when the user wants to convert audio format (wav/mp3/flac/m4a/ogg/aac), transcode or re-encode audio files, adjust audio sample rate, bitrate, channels, compress audio files, resample or downsample audio, prepare audio for downstream tasks, or do any audio preprocessing.

# LAS 音频格式转换(`las_audio_convert`)

将 TOS 上的音频文件转换为指定格式(wav/mp3/flac),可通过 `extra_params` 传入 ffmpeg 参数调整采样率、声道数等。

## 设计模式

本 skill 主要采用:
- **Tool Wrapper**:封装 `lasutil` CLI 调用
- **Pipeline**:包含 Step 0 → Step N 的顺序工作流

## 核心 API 与配置

- **算子 ID**: `las_audio_convert`
- **API**: 同步(`process`)
