iPerf vs CreamAudio Recorder

This app is an iOS port for iperf3, which is the most commonly used network testing and performance computation tool. Iperf is a tool to measure maximum TCP bandwidth, allowing the tuning of various parameters and UDP characteristics. Features - Compatible with iperf3 in other platforms - Run as iperf3 client or server - Customize iperf3 arguments - Display Wi-Fi interface link speed and SSID IMPORTANT This application is based on iperf 3.21, which is not compatible with the legacy iperf (version 1.x and 2.x). And it may have some minor issues with the other iperf3 versions.

CreamAudio Recorder captures audio the way engineers and musicians need it: straight from the hardware, with nothing added and nothing taken away. MEASURE mode — unprocessed, by default Every recording starts in MEASURE mode, which turns off automatic gain control, noise suppression, and EQ so what hits the file is the raw, linear signal from the input — the built-in mic, or an attached USB/Thunderbolt/class-compliant audio interface. No smoothing, no "enhancement," no surprises — just a clean, faithful, repeatable recording. Built for acoustic measurement, instrument capture, room tone, and any use where accuracy matters more than a processed sound. DSP mode — Apple's stereo mic, when you want it (iPhone/iPad) Flip the switch to DSP mode on iPhone or iPad to hand the signal to Apple's mic-array processing and unlock true stereo capture from the built-in microphones, with the OS's natural-sound tuning (AGC/EQ/noise suppression) applied — good for interviews, ambience, and everyday recording where a fuller, processed sound is what you want. DSP mode only ever applies to the built-in mic; plug in an external interface and the signal is always the raw, unprocessed one. Recording Set your format before you hit record: WAV (24-bit PCM) or AAC (.m4a) at your choice of 96/128/192/256 kbps, recorded directly with no intermediate conversion Share a take straight from the app via the standard system share sheet — AirDrop, Messages, Mail, Save to Files, or any other app — in the format you recorded (WAV by default) Record-level gain boost up to +24 dB, with optional auto level Live stereo metering: switchable analog VU needle or segmented LED ladder Background recording continues when the app is backgrounded or the screen locks Universal: macOS, iPhone, and iPad CreamAudio Recorder is a paid app — a single purchase unlocks every feature described here. There are no subscriptions and no in-app purchases; all features are included.
