Recording the audio we need

Sometimes you may not want the entire audio file you're working with. The duration and offset parameters of the record() method can help with this.

After exploring your dataset, you find there's one file, imported as nothing_at_end which has 30-seconds of silence at the end and a support call file, imported as out_of_warranty has 3-seconds of static at the front.

Setting duration and offset means the record() method will record up to duration audio starting at offset. They're both measured in seconds.

    Let's get the first 10-seconds of nothing_at_end_audio. To do this, you can set duration to 10.

    Let's remove the first 3-seconds of static of static_at_start by setting offset to 3.
