I thought I figured out why whisper.cpp 1.42 would keep crashing. Perhaps it was silence in the audio so I automatically removed it but still it crashed. This is getting quite frustrating. Anyway here's how to automatically remove any silence segments of 4 seconds or more from audio.
mkdir output ; for f in *.opus ; do ffmpeg -i "$f" -c:a libopus -vbr off -b:a 32k -ar 48000 -af "silenceremove=start_periods=1:stop_periods=-1:start_threshold=-50dB:stop_threshold=-50dB:start_silence=1:start_duration=2:stop_duration=4:detection=peak",dynaudnorm output/"$f" ; done
it took about an hour to process and showed the following but yet running whisper.cpp on it still crashed size= 470441kB time=32:49:17.45 bitrate= 32.6kbits/s speed=35.7x video:0kB audio:461553kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 1.925659%
Original audio is 32:53:43 After any silence over 4 seconds was automatically removed which took about an hour to do Audio became 32:49:17
4 mins and 26 secs was removed of silence. Not sure how many silence parts there actually were.

Telegram has no known backdoors and, even though it is come in for criticism for using proprietary encryption methods instead of open-source ones, those have yet to be compromised. While no messaging app can guarantee a 100% impermeable defense against determined attackers, Telegram is vulnerabilities are few and either theoretical or based on spoof files fooling users into actively enabling an attack.
That strategy is the acquisition of a value-priced company by a growth company. Using the growth company's higher-priced stock for the acquisition can produce outsized revenue and earnings growth. Even better is the use of cash, particularly in a growth period when financial aggressiveness is accepted and even positively viewed.he key public rationale behind this strategy is synergy - the 1+1=3 view. In many cases, synergy does occur and is valuable. However, in other cases, particularly as the strategy gains popularity, it doesn't. Joining two different organizations, workforces and cultures is a challenge. Simply putting two separate organizations together necessarily creates disruptions and conflicts that can undermine both operations.
