I am processing audio chunks programmatically by using the ffmpeg library for C#. First I divide the input audio of .wav format into chunks of 1 minute each (I can't process the whole audio for specific reasons), then prepend it's header to each chunk so it can be recognized and processed, then I get raw PCM of each chunk and replace some parts of PCM with sine wave data (adding beeps) and then I transform that PCM chunks to mp3 chunks and write those to stream. The final process of concating audio parts is *NOT *performed by ffmpeg, I just write data chunks to the destination stream. I am facing the problem that there are noticeable transitions between 1 minute chunks in result audio(clicks/silence/change of volume/shifting). How can I smooth out the start/end of each chunk so when I'm putting them together there are no noticeable transitions? Here are the commands that being generated by library:
To get PCM: -i "\\.\pipe\..." -ar 8000 -f s16le "\\.\pipe\..." -y To transform PCM to mp3: -f s16le -ar 8000 -ac 1 -i "\\.\pipe\..." -b:a 128k -f mp3 "\\.\pipe\..." -y -- This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
