​PRODUCTION SOUND RESOURCES
Tools & Calculators
Tools and calculators exist to remove guesswork. When the math is done once and done correctly, decisions become faster and more confident. This section is about practical utilities you can trust on set.​
Goal
Make informed decisions quickly without mental math or assumptions.
Method
Use simple tools that reflect real world production sound needs.


​
Result
Fewer mistakes, faster setups, and more predictable outcomes.
​

Utility Focused
Set Friendly
Decision Support
Tools in One Sentence
Good tools answer questions before they turn into problems.
When to Use Tools and Calculators
​
Estimating recording time or file sizes
Planning media requirements
Confirming limits before hitting record
Double checking assumptions
​
Tools are there to support decisions, not replace experience.
Recording Time Calculator

Estimate how long you can record based on track count, sample rate, bit depth, and available media.

Use this to:
Avoid running out of space mid day
Plan media swaps
Set realistic expectations
File Size Estimator

Calculate expected file sizes for a day or a shoot.

Helpful when:
Delivering large track counts
Coordinating with post
Managing backups​
Timecode End Time Calculator

Calculate an end timecode based on a start timecode and a duration.

Use this to:
• Predict where a long take will land on the timeline
• Estimate end time for a roll or card across multiple takes
• Double check timecode math during troubleshooting
• Validate drop frame workflows for 29.97 DF and 59.94 DF
Unit Converter

Convert between meters, feet, inches, and centimeters.

Use this to:
Plan cable runs and antenna placement distances
Estimate boom reach or talent to receiver spacing
Sanity check measurements from art department or camera
Communicate distances quickly when departments use different units
What These Tools Are Not

They do not replace experience
They do not override production requirements
They do not account for every edge case

They are guides, not guarantees.
