To determine the step between the notes in the audio sample, you would need to analyze the pitch change. However, since I can't listen to audio, I can't provide a definitive answer.
If the notes are adjacent on a piano keyboard (e.g., from C to C# or B to C), it would be a half step. If there is one key (or whole note) between them (e.g., from C to D), it would be a whole step.
If the notes are the same, it would be a same pitch, and if the notes are several notes apart, it would be a leap across many steps.
Please make an assessment based on your listening.
