Audio Tone Generator Plus vs Kestrel Sight

"Audio Tone Generator Plus" is an integrated sound signal generator app that produces various audio reference tones. It can be used in a wide range of fields as a reference sound source for audio system testing, sound tuning, hearing testing, and more. This app features four types of signal generators for producing sine wave signals, frequency sweep signals, chirp signals, and colored noise with octave band filters. - Sine Wave Generator: Generates a pure tone with high DVD-quality precision and 0.1 Hz frequency accuracy. The frequency can be set using four presets or keyboard input. - Frequency Sweep Generator: It produces a linear sine wave frequency sweep/warble signal. The start and stop frequencies can be adjusted using three presets or keyboard input. Upward and downward sweeps are possible. - Frequency Chirp Generator: It produces a very short sweep signal with linear or exponential frequency change. The start and stop frequencies can be adjusted using three presets or keyboard input. The generation time of the chirp signal and the start delay time can be adjusted. - Colored Noise Generator with Octave Band Filter: Generates white, pink, red, blue, purple, and gray noise. It can also generate 1/1 and 1/3 octave band colored noise with a user-configurable octave band filter. Multiple selections of arbitrary bands are possible and are used for the detailed analysis of specific frequency bands. A burst signal can be output with four different duty ratios. Features: - Sine wave generator (Sine): Sine wave signal (Preset frequencies: 200Hz, 1kHz, 2kHz, 8kHz) - Frequency Sweep generator (Sweep): Sine wave frequency sweep/warble signal (Preset frequencies: 20Hz - 20kHz, 200Hz - 2kHz, 2kHz - 8kHz, transition time: 30, 60, 120, 180sec), upward/downward sweep playback - Colored Noise generator with octave-band filter (Noise): White noise, Pink noise, Red noise (Brown noise), Blue noise, Purple noise and Gray noise. Octave-band noise generation by 1/1 or 1/3 octave-band filer (center frequency: 63Hz - 8kHz / 50Hz - 10kHz), burst playback with duty ratio of 10/25/50/75%. - Chirp signal generator (Chirp): Short-time sweep signal (transition time: 0.1 - 1.0sec, start delay time: 1 - 10sec, frequency variation curve: Linear/Exponential.) - Configurable frequency range: 20Hz - 21kHz - Frequency input by keyboard in units of 0.1Hz - Preset frequency customization function. - Playback time control: 30sec/60sec/2min/3min/15min/60min - Output gain control. - Output channel selection: LR/L/R - Output phase control: 0/180 degree - In-phase/Out-of-phase. Applications: - Sound testing for loudspeakers and headphones. - Testing and tuning for Audio amplifiers, equalizers and many other Audio equipment. - Acoustics testing. - Frequency response measurement. - Sound insulation level measurement. - Indoor sound field distribution measurement. - Reverberation time measurement. - Sound masking. - Relaxation and meditation. - Hearing test. Note: - Please be careful that the high-frequency signals of high volume in continuous may damage the loudspeakers, even if your ears do not perceive it as being too loud. - The chirp signal is a sweep signal of extremely short duration, so it does not guarantee a playback frequency in the specified range. - If no frequency is selected in the octave-band noise generation, the signal output will be silent. - When using this application with wireless communication such as Bluetooth or AirPlay, there may be cases that limitation of the playback frequency, lowering the output level and irregular noise, etc., may occur under the influence of wireless environment, communication equipment and communication state. Please note that this is not to guarantee that this application operates as configured specifications under the wireless communication.

Kestrel Sight brings professional packet capture analysis to iPhone and iPad. Every byte is processed on-device — Kestrel makes no network connections, and collects no analytics. WHAT'S NEW CSV Export — Three profiles: Summary (Excel-ready, 9 columns), Detailed (every protocol layer, ~24 columns), Flow (one row per conversation). Export everything or just bookmarked packets, with bookmark notes preserved as columns. Filenames indicate scope at a glance. Smart Bookmarks — Bookmarking a flow, host, DNS query, or stream now resolves to all related packets in CSV exports. Tap "View" on any bookmark to jump straight to that data with the right filter applied. Expanded Protocol Detection — Added classification for SMB, mDNS, DHCP, NTP, SNMP, SSDP, and QUIC. Dashboard Navigation — Every dashboard widget is now interactive. Tap Total Packets to open Packets, tap a Top Talker to filter Hosts to that IP, tap "TCP" in Protocol Distribution to filter the Packets list, and so on. Subtle chevrons indicate what's tappable. Haptic Feedback — Bike-spoke clicker feedback when scrolling lists. Crisp tap feedback on buttons. Adjustable row density. New filter-bar toggle cycles between Classic, Compact, and Comfortable layouts in the Packets browser. Compact fits ~22 rows per phone screen; Comfortable mirrors iOS Mail's two-line look. On iPad, Classic uses a denser style single-line row. App Switcher privacy. Sight now hides the analysis surface behind the Kestrel logo whenever the app leaves the foreground, so the iOS App Switcher thumbnail and AirPlay mirroring. Faster first-tap haptic response and internal robustness improvements. CORE FEATURES Dashboard — Protocol distribution, encryption stats, top talkers, session summary Packets — Browse and filter with detailed per-layer inspection Raw Data Search — Query any byte sequence in its original form Flows — Bidirectional reconstruction with byte counts, packet counts, timing Hosts — Per-IP profile with traffic stats, port activity, connection mapping DNS — Extract and search all DNS queries and responses Streams — TCP stream reassembly with full-content viewer (auto-runs under 1 GB) Timeline — Visual event timeline with filtering Audit Log — SHA-256 file hashing and session audit log included in PDF exports CAPACITY Up to 1 GB — Full feature set with automatic TCP reassembly Over 1 GB — TCP reassembly disabled; packets, flows, hosts, DNS, and timeline remain fully functional Over 2 GB — Application performance may degrade SUPPORTED FORMATS PCAP, PCAPNG IDEAL FOR SOC analysts reviewing captures away from the workstation Network administrators troubleshooting connectivity Incident responders triaging captures in the field Penetration testers reviewing engagement data Educators and students learning protocol behavior PRIVACY AND SECURITY Zero network access — no outbound connections No analytics, tracking, or advertising Kestrel is designed as an analytical and educational starting point. Always verify findings independently before acting on them. No software can guarantee absolute security; follow your organization's evidence-handling procedures when working with sensitive captures. IMPORTANT NOTES Kestrel analyzes pre-captured PCAP files only — live capture is not permitted within iOS by the platform itself. Screenshots may combine demo and real data. Large captures may extend load times. Devices with 8 GB RAM or more are recommended for multi-gigabyte files. The demo uses fabricated sample packets.
