Neoductiontools, all audio tools you need, always at hand.

This application is a gift from Neoduction to all audio professionals. We started with 12 simple applications, and this is just the beginning of something bigger we want to build for you.
Some of these tools help with very simple calculations that may seem obvious. Our aim is for this app to serve all audio engineers across all levels of knowledge.

Now enjoy the new In-App purchase: Sound Meter. A Class 2 device with presets for iPhone 6s, iPhone 6s Plus, iPhone 6, iPhone 6 Plus, and iPhone 5s. A, C, Z frequency weighting and LCpk, Lf, Ls, Le, Leq1', Leq1" time weighting for a deep analysis of the sound pressure. Soundmeter prints a defined graphic which can be sent to an e-mail as an xml file and includes a feature to schedule time/level programmable measurements.

We are committed to developing Neoductiontools for professionals and audio enthusiasts alike, and we’d love to hear from you. Please feel free to suggest new tools that you find interesting for your work and we’ll try to accommodate these.
You can contact us at propose@neoduction.com
We all hope you enjoy and find use to Neoductiontools in your day-to-day tasks.

SOUND METER: A Class 2 device with presets for iPhone 6s, iPhone 6s Plus, iPhone 6, iPhone 6 Plus, and iPhone 5s. A, C, Z frequency weighting and LCpk, Lf, Ls, Le, Leq1', Leq1" time weighting.

WIRE ATTENUATION; Calculate the loss of high frequencies in the transport of an electrical signal due to the impedance, capacitance and the length of the signal cable.

SPEED OF SOUND: Calculate the variations in the speed of sound caused by the air temperature in degrees C, and Kº Fº. The result is given in several different units.
Do you know the speed of sound in the North Pole? How is it different during a 20:00 pm show at the location where I'm doing soundcheck at 15:00 pm?

SABINE T-60: A way to roughly estimate the decay at 60 dB of reverberation time, knowing the dimensions, key materials and room shape.

BPM / DELAY: Calculate the time in ms of musical notation of a known tempo. You can also tap if you don’t know it.

FILE WEIGHT: Do you have space on your hard disk to start recording this multitrack project? Find out safely.

SAMPLES / FREQUENCY: This calculator will be useful to know the variations in the wavelength of a frequency as a function of temperature. e.g., how many samples make up an 18KHz wave at 48KHz?

OUTPUT IMPEDANCE: The eternal question of how many speakers can be connected to this amplifier and in what way, and the estimated power applied accord to his impedance, also you can check the power received by each speaker.

STEREO PATTERNS: Calculate the coverage areas of a pair of stereo microphones according to their polar patterns, placement and spacing of the orchestra.

EIGENMODES: Calculate the eigenmodes of a room or space according to its dimensions. Very interesting if you're building a home studio or want to know how a 140 m² stage parallel to the ground influences your sound work.

Q FACTOR / OCTAVES: Some of us prefer to know the bandwidth of a parametric eq in octaves.

CLUSTER DELAY: Calculate the delay necessary to position two clusters depending on the temperature, the distance between them and the Hass effect.

FREQUENCY / NOTE: Calculate the direct and inverse relationship between frequency and musical note and its deviation, taking into account the overall pitch of the A4 with 440, 441, 442, 443 or 444 Hz.
