Audacity Forum

Just got the ffmpeg not found message, only just happened between exporting multiples, so I promptly downloaded the necessary file for the library, BUT, Audacity cant see it or pick it up on my laptop. I have downloaded it three ...

Actual export commands (didn't know it mattered since I'm using the same command in Audacity and ffmpeg): - fhgaacenc --vbr 3 --ignorelength - "%f" - ffmpeg -i audio.ac3 -acodec pcm_s16le -f wav - | fhgaacenc --vbr 3 --ignorelength - out.m4a or ffmpeg -i audio.ac3 ...

Audacity 2.0.3 will no longer record. I am using Windows XP 32 23:32:55: Audacity 2.0.3 23:32:57: Trying to load FFmpeg libraries... 23:32:57: Trying to load FFmpeg libraries from system paths. File name is 'avformat-52.dll'. 23:32:57: Looking up PATH environment variable... 23:32:57: ...

Sample rate is 48 KHz after import, and after export also (both in Audacity and ffmpeg).

... across was the Default Sample Depth which is for recording. Anyways, channels panel on the left says 16-bit. This is a limitation of Audacity's FFMpeg import - it is always 16 bit integer. When you import the file, does the track say that the sample rate is 48000 Hz?

... -quality n -options - "%f" ???? That is not a valid command??? What is the actual command that you are using? Command used in ffmpeg: ffmpeg -i input.ac3 -acodec pcm_s16le -f wav - | external-encoder -quality n -options - output.xxx Again, what is the actual command that you ...

Steve, check my first post in this thread. I explained what I'm doing there. But to recap, I am transcoding AC3 5.1 (.ac3 file) to AAC 5.1 (.m4a file) through external encoder (piping). As I said, the commands used are mentioned in my initial post. Also, please disregard the part regarding 5.1 vs St...

You're painting a very different picture to what your other post suggested.

How are you doing that? What is the the original format, what is the final format, and how are you accomplishing the transcoding?

Steve, Thx for your replies. Very informative stuff. Though as discussed in the other thread (let's continue this here from now on), the bitrate discrepancy is not what one would expect. I mean as I said, the lower bitrate corresponds to the dithered audio, and higher bitrate to the untouched audio....
