Code Quality Issues: Redundant Conditionals and Low Function Quality

[sourcery-ai]

The Sourcery AI bot has identified several code quality issues in the current codebase:

1. Remove Redundant Conditional: There are instances of redundant conditionals that should be removed to improve code clarity and efficiency. More details can be found in the Sourcery documentation.

2. Low Code Quality in Function: A specific function has been flagged with a low code quality score of 10%, which is below the acceptable threshold of 25%. This score is determined by factors such as method length, cognitive complexity, and working memory.

Suggested Improvements:

• Refactor the Function: Break down the function into smaller, more manageable pieces. Ideally, each function should be less than 10 lines.
• Reduce Nesting: Consider using guard clauses to simplify the logic and reduce nesting.
• Scope Variables Tightly: Ensure that variables are used within a limited scope to enhance readability and maintainability.

These improvements should be addressed in a separate pull request to maintain focus on the original goals of the current pull request.

This is referring to the read() function inside audiofile/core/io.py, in which we have a lot of conditional statements for duration and offset.
