Spektral Mobileはどんなアプリ？
Spektral Mobileは、音響エンジニア向けにリアルタイムで音響解析を行うアプリです。
対数スケールの周波数で音の広がりを可視化するRTAや、時間と周波数の変化を熱分布で捉えるスペクトログラフが備わっています。過去の履歴を背景に表示するSPLメーターも同時に動くため、空間の音の状態を多角的に把握できます。ハウリングの原因となる特定の周波数を自動で検出し、カットすべき周波数やQ値を提案する機能も備わっています。ピンチ操作で範囲を広げたり縮めたりする操作性や、暗い会場でも視認しやすい黒を基調とした画面構成が採用されています。
ライブ会場の音響調整やスタジオでの機材セッティングなど、正確な数値に基づいた判断が必要な場面で便利です。特定のノイズを見つけ出して瞬時に対策を講じたい現場の技術者にとって、確かな判断材料を提示する道具となります。

Spektral Mobileの注目ポイント
対数スケールによるRTA
周波数を対数スケールで可視化するRTAが搭載されています。特定の帯域を細かく追いながらリアルタイムの音響変化を捉えることができます。
熱分布で捉えるスペクトログラフ
時間と周波数の変化を熱分布として表示するスペクトログラフです。過去の動きが視覚的に残るため、音の変化を追いながら分析が行えます。
履歴を表示するSPLメーター
過去の履歴を背景に映し出すSPLメーターが備わっています。会場の音量推移を把握しながら現在のレベルを正確に測る際に役立ちます。
ハウリング原因の特定とカット案
ハウリングの原因となる周波数を特定し、具体的なカット案を表示します。該当する音階や中心周波数を提示するため、迅速な調整が行えます。

LIMIT GUARD HEADROOM METER
Limit Guard now shows your headroom on a meter: twelve blocks from +6 to -6 dB, counting down as the room runs out, the scale engineers already know. Around it, a marker for the last minute's level shows which way the average is heading, a tick shows where the Leq will sit in five minutes, and when you are close or over, a recovery line tells you what level to hold under and for how long.
It pulses amber only while the margin is shrinking, and holds steady while you are pulling it back. Solid red means over. Every state carries a number as well as a colour, so it reads at a glance from the desk.
The warning margin is now yours to set, at 1, 2, 3 or 6 dB, from the Limit Guard panel on the SPL page.
REMOTE MONITORING
Readings are only marked as synced once iCloud has confirmed them. Previously a phone could report "All readings synced" while iCloud was refusing the uploads, and the readings were discarded. Spektral now keeps anything iCloud has not accepted, and tells you plainly if it is being refused rather than simply waiting for a connection.

RING-OUT
Spektral now listens for feedback while you work. It looks for a frequency
that is building rather than one that is merely loud, so a bass note or a
mains hum cannot set it off. When it finds one you get the frequency, the
musical note, and a suggested notch: centre, Q and cut. Confirmed rings
collect in a list you can work through.
A PROPER SPL METER
The SPL page has been rebuilt for iPhone and iPad. Leq over 1 minute,
15 minutes, 30 minutes, 1 hour and 8 hours all run at once, with three hours
of level history on one graph and min, max and average underneath.
A, C and Z weighting. Fast, Slow and Impulse.
LIMIT GUARD
Set a limit and a window, and Spektral forecasts how long you have before
you reach it, so you find out while you can still do something about it.
CALIBRATION
A sensible default for the built-in microphone out of the box, and a guided
calibration against an acoustic calibrator when the number has to be right.
IDENTIFY
Choose how many peaks get labelled, down to just the single strongest one.
ALSO
• Pink noise never starts on its own
• Readings say plainly when they are uncalibrated, rather than presenting
dBFS as though it were dB SPL
• Layout fixes across iPhone sizes: tighter toolbar, symmetric RTA gutters,
spectrograph range tabs
