cách ghép nhiều file audio thành file dài bằng audacity

To splice multiple short audio files into one long file in Audacity, follow these steps:

Import Your Files: Open Audacity and go to File > Import > Audio. Select all the audio files you want to combine. Each file will appear as a separate track.
Align Tracks End-to-End:
- Select all tracks by pressing Ctrl + A (or Cmd + A on Mac).
- Go to Tracks > Align Tracks > Align End to End. This will arrange the tracks sequentially.
Adjust as Needed: If you want to add silence between tracks or make other edits:
- Use the Generate > Silence option to insert gaps.
- Use the Time Shift Tool (double-headed arrow icon) to manually adjust the position of tracks.
Mix Down to One Track: Once everything is aligned, go to Tracks > Mix > Mix and Render. This will combine all tracks into a single track.
Export the Combined File: Finally, go to File > Export and choose your desired format (e.g., MP3, WAV).
