Delay Tower Time Alignment MS Distance Calculator

Audit actual main/delay-speaker path and electronic arrival offsets across seats, retaining negative required offsets and multi-seat spread; not AV sync scalar, precedence recommendation or a venue-wide phase guarantee.

Description

Delay alignment compares acoustic paths and electronic latencies at each seat.

Delay alignment compares acoustic paths and electronic latencies at each seat. One delay value may not align every location.^[1]

Enter aligned nonempty nonnegative paths, positive sound speed and nonnegative latencies. Return signed offsets, binary negative-offset flags and max−min spread.

When to use Delay Tower Time Alignment MS Distance Calculator

Use Delay Tower Time Alignment MS Distance Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. Negative offsets indicate advancing the modeled source would be needed. No precedence setting or venue-wide phase guarantee is provided.

Prepare the actual venue, production, inventory or financial records requested. Confirm units and supply applicable local limits or verified catalog values.

How to use Delay Tower Time Alignment MS Distance Calculator and understand its results

Prepare the actual venue, production, inventory or financial records requested. Confirm units and supply applicable local limits or verified catalog values.
Enter mainSpeakerPathDistancesM, delaySpeakerPathDistancesM, speedOfSoundMSecond, mainElectronicLatencyMs, delayElectronicLatencyMs using the field table and calculation rules, then run the tool.
Read requiredAdditionalDelayMsBySeat, delaySignRequiresAdvancingSourceFlags, seatDelaySpreadMs. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
mainSpeakerPathDistancesM	Main speaker path distances m	list of number	Required
delaySpeakerPathDistancesM	Delay speaker path distances m	list of number	Required
speedOfSoundMSecond	Speed of sound m second	number	Required
mainElectronicLatencyMs	Main electronic latency ms	number	Required
delayElectronicLatencyMs	Delay electronic latency ms	number	Required

Enter aligned nonempty nonnegative paths, positive sound speed and nonnegative latencies. Return signed offsets, binary negative-offset flags and max−min spread.

extraDelayMs=1000(mainPath−delayPath)/soundSpeed+mainLatency−delayLatency

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
requiredAdditionalDelayMsBySeat	Required additional delay ms by seat	list of number
delaySignRequiresAdvancingSourceFlags	Delay sign requires advancing source flags	list of number
seatDelaySpreadMs	Seat delay spread ms	number

Limitations and assumptions

Negative offsets indicate advancing the modeled source would be needed. No precedence setting or venue-wide phase guarantee is provided.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Speaker Array Coverage Angle Venue Width Calculator: A centered audience-plane footprint determines an ideal horizontal angle. Measured speaker coverage is a separate input. For a complementary task, use RF Antenna Distribution Splitter Loss Count Tool: RF insertion losses add along a serial distribution path. Received-level margin uses measured input and an explicit receiver minimum.
