Serialization/deserialization: How long it takes to interpret a message and convert it into a usable form.Similarly, the receiving machine’s network card must push the message up through the operating system and into the receiving application. When an application wants to send a message to another machine, this must happen, and it can be influenced by numerous factors, including computer load, firewalls, and network traffic. Network stack: How long it takes a message to be routed through the operating system and network driver to the network card itself.Network/transmission latency: Physical distance and network infrastructure can add significant delays to your messages (both to and from Deepgram).

In mathematical terms, it is the difference between the audio cursor (the number of seconds of audio you have currently submitted we’ll call this X) and the latest transcript cursor ( start + duration we’ll call this Y). To better take into the account of latency and packet loss, especially for cross country file transfer, we at Tachyon have built a file transfer time calculator.In general terms, real-time streaming latency is the time delay between when a transfer of data begins and when a system begins processing it. Latency and Packet loss can increase file transfer time by a 1000x, when we send files to our editors in Munic, even though our own speed is great it takes days instead of hours. Packet loss is caused by factors including: faulty routers, lousy Wi-Fi signal, bandwidth restrictions, and network congestion. These packets can be lost or dropped for a variety of reasons, and when this happens the packet needs to be resent, and thus high packet loss can lead to slow file transfer. Instead they are first broken up into bite sized pieces of information called packets which are then sent to and reconstructed into the complete file at the destination. When files are sent across the internet, they aren't sent in their entirety in one go. Latency is impacted by a number of factors including: distance from source to destination, the transmission mediums used such as WAN or fiber optic cables, and the routers used. Usually when people talk about network latency they are referring to Round Trip Time (RTT).

Latency measures the time it takes for some data to get to its destination across a network.

In this article we explain those two factors and provide you a way to take them into account when calculating file transfer time. If your destination is geographically far away, for example cross-country or maybe even located in another continent two other often missed factors can dramatically increase the file transfer time: latency and packet loss. File transfer time isn't just dependent on file size and bandwidth.
