Added Start time property

[TanvirMobasshir]

Release Notes - Pydub v0.25.2

New Features

AudioSegment Class

• Added a new property: start_time
  • Default value: 0
  • The start_time property is now available for the AudioSegment class.
  • Updated automatically when using the split_on_silence() function.
  • During the creation of multiple chunks, start_time reflects the starting time of its parent AudioSegment object.

How to Use

from pydub import AudioSegment

# Create an AudioSegment instance
audio = AudioSegment.from_file("example.mp3")

# Access and modify the start_time property
start_time = audio.start_time  # Get the current start time, default: 0

# Use split_on_silence() to update start_time during chunk creation
chunks = split_on_silence(audio)

for chunk in chunks:
    print(f">> {chunk.start_time}, {chunk.duration_seconds*1000+chunk.start_time}")

Result:

>> 503, 3338.0
>> 3338, 6179.0
>> 6179, 7632.0
>> 7632, 13930.0
>> 13930, 18141.0
>> 18141, 20653.0
