Talking Tuner vs SonoBus

HotPaw Talking Tuner is a hands-off, sound-activated, talking, chromatic, musical instrument tuner. It talks to tell you if your instrument is in tune or not; so you don't even have to look at it or touch the display. Talking Tuner uses speech synthesis, and works with or without VoiceOver being enabled. This app was created because I received a request to develop an iPhone app which could help a vision-challenged individual tune their musical instrument. This app is the result. With the Auto-Speak switch turned on, Talking Tuner will listen for a note to be played, and then, after waiting for the end of the sound (so as not to talk over it), will speak the note name, and how many cents sharp or flat the end of the note is estimated to be. Using headphones may help make it easier to hear what this app is saying while tuning. Make sure to turn the volume up high enough to hear it. The pitch estimation algorithm works best for notes between 2 octaves below Middle-C to 2 octaves above Middle-C. It may not work as well for very low notes, very high notes, or with any background noise, harmony, or accompaniment present. The default tuning resolution is about +- 3 cents (3/100ths of the pitch difference between semitones). Optional higher resolution tuning settings may result in a slower tuning response.

SonoBus is an easy to use application for streaming high-quality, low-latency peer-to-peer audio between devices over the internet or a local network. Simply choose a unique group name (with optional password), and instantly connect multiple people together to make music, remote sessions, podcasts, etc. Easily record the audio from everyone, as well as playback any audio content to the whole group. Public groups are also available, for those interested in connecting to new people. Connects multiple users together across the internet to send and receive audio among all in a group, with fine-grained control over latency, quality and overall mix. Use it on your desktop or in your DAW, or on your mobile device. You can also use it locally on your own LAN to send audio among your devices with low latency. Works as a standalone application. as an AudioUnit v3 plugin with a compatible host app, or via Interapp-Audio. You can connect to others using SonoBus on any of the other platforms it runs on. Easy to setup and use, yet still providing all the details that audio nerds want to see. Audio quality can be instantly adjusted from full uncompressed PCM down through various compressed bitrates using the low-latency Opus codec. SonoBus does NOT use any echo cancellation, or automatic noise reduction in order to maintain the highest audio quality. As a result, if you have a live microphone signal you will need to also use headphones to prevent echos and/or feedback. SonoBus does NOT currently use any encryption for the data communication, so while it is very unlikely that it will be intercepted, please keep that in mind. All audio is sent directly between users peer-to-peer, the connection server is only used so that the users in a group can find each other. For best results, and to achieve the lowest latencies, connect your device with wired ethernet to your router. Little known fact, you can use USB ethernet interfaces with your iOS device using the proper adapter (USB camera connection kit, or natively with USB-C apple devices). It *will* work using WiFi, but the added network jitter and packet loss will require you to use a bigger safety buffer to maintain a quality audio signal, which results in higher latencies, which may or may not be acceptable for your use case.
