Calculators
Planning tools for mixing & music production, with visible assumptions and units.
Calculate the output level above threshold from an input level and a compressor ratio. This arithmetic model assumes a hard knee and does not model attack, release, makeup gain, or other compressor behavior.
Estimate the time to upload audio files from their total size and your available upload speed. The estimate assumes a steady connection and uses decimal file-size and network-rate units.
Convert an audio frequency into its cycle period, showing how long one waveform cycle takes.
Compare two audio signal peak voltages as a linear ratio and decibel difference. Enter both peak voltages in volts to see how many times larger the second signal is than the first.
Convert a sample count and sample rate into elapsed audio time. Choose seconds or minutes for the result.
Calculate musical delay time in milliseconds from a tempo and note subdivision. Choose a subdivision to find the matching beat-synchronized delay interval.
Estimate working storage for a shared music production project from session files, collaborators, and retained versions. The estimate assumes each collaborator has a full working copy and that retained versions are full copies.
Estimate the buffer-related round-trip delay of a digital audio workstation in milliseconds from audio buffer size, sample rate, and input/output buffer passes. This simplified estimate excludes interface, plugin, driver, and system latency.
Convert a decibel level difference into the corresponding linear amplitude ratio using the standard 20 log10 relationship.
Estimate a mixing project quote from your hourly rate, estimated mixing hours, revision hours, and any additional project expenses. This worksheet adds those costs without applying a market-rate benchmark.
Estimate an uncompressed PCM mix export's file size from duration, sample rate, bit depth, and channel count. The estimate excludes metadata and container overhead.
Estimate the hands-on time for one mix revision from the number of requested changes, average time per change, and review complexity. This planning estimate excludes client response time, exports, and unrelated production work.
Estimate the electricity consumed by audio mixing and music production equipment during a typical work period. Enter the combined power draw of the equipment, daily operating time, and days used per week to calculate estimated weekly energy use in kilowatt-hours (kWh).
Estimate a mixing session budget from hourly engineer and studio rates, session hours, preparation time, and a complexity factor. This planning estimate assumes the same hourly rates apply to session and preparation time.
Calculate the percentage increase or decrease between an original tempo and a new tempo, entered in beats per minute (BPM).
Calculate a tempo-synced note-duration reference in milliseconds for exploring reverb pre-delay settings. Use the result as a timing reference and adjust by listening.
Estimate uncompressed PCM audio data rate from sample rate, bit depth, and channel count. The result is the audio payload rate before file-container overhead or compression.
Estimate uncompressed storage for stereo audio stems in decimal gigabytes from stem count, duration, sample rate, and bit depth.
Find the geometric distance from a centred listening position to each monitor from speaker spacing and perpendicular setback. The two monitors share a horizontal front line. This symmetric geometry worksheet does not recommend an acoustically optimal position.
Estimate the total face area covered by acoustic treatment panels from their dimensions and quantity.
