FixPitch是一款专为Adobe After Effects设计的音频处理脚本，可在调整视频速度时自动保持声音自然音调，解决AE中变速导致声音变尖或变低的问题。插件基于FFmpeg音频处理引擎，支持Time Stretch、Time Remapping、多段变速、预合成音频处理等功能，可一键修复音频音高，并提供无损WAV处理流程，让视频变速与声音调整更加高效。
Changing playback speed while keeping the original pitch isn’t a simple filter — it requires rebuilding the audio waveform through a dedicated time-stretching algorithm. After Effects’ native audio engine doesn’t include this kind of processing. FixPitch hands this calculation to FFmpeg, a free, open-source audio/video engine used by professional tools industry-wide, then brings the corrected audio straight back into your composition.
