Huge audiobook collections from various sources video / audio have various sample rates which is irrelevant but mixing various sample rates 44.1kHz, 48kHz creates a problem of chapter times being not accurate.

Opus compression does not depend on the input sample rate; timestamps are measured in 48 kHz units even if the full bandwidth is not used.

1) Freac when you attempt to Encode to a single file opus chaptered audiobook and you see verious sample rates stop. First encode audio files with videomass before loading them into freac.

Preset filter to use in videomass and output to opus
-vn -c:a libopus -b:a 32k -ar 48000 -af dynaudnorm,aformat=channel_layouts=mono

-ar 48000 (is mandatory) and mono (is highly recommended)

dynaudnorm = Dynamic Audio Normalization so corrects low volume (optional)

Don't forget with hundreds of chapters you can't access them all on VLC on your computer so need to use VLC on your phone.

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.

The messaging service and social-media platform owes creditors roughly $700 million by the end of April, according to people briefed on the company’s plans and loan documents viewed by The Wall Street Journal. At the same time, Telegram Group Inc. must cover rising equipment and bandwidth expenses because of its rapid growth, despite going years without attempting to generate revenue.
