Fastest way to concatenate list of audio files of different format?
ffmpeg -i a.mp3 -i b.wav -i c.mp3 -i d.aac -i e.mp3 -i f.mp3 -filter_complex concat=n=4:v=0:a=1[a] -map [a] -codec:a libmp3lame -b:a 256k vout.mp3
This is the command I'm using currently to concatenate a list of audio files. Is there any faster way to merge songs using ffmpeg ?

No, there is no faster way.
Since you are concatenating files with different codecs and containers, you have to pass the audio through a concat filter, which requires re-encoding.

Thanks for your reply. I'm currently developing an android app with FFmpeg integrated. for concatenating 2 audio file my phone taking about 5 minutes with this command. But another app already in the play store doing the same in a minute with FFmpeg. So, I think I have to improve my coding side to improve encoding speed.

Try a different encoder. If you prefer MP3 try shine. From the shine website:
shine is a blazing fast mp3 encoding library implemented in
fixed-point arithmetic. The library can thus be used to performe super
fast mp3 encoding on architectures without a FPU, such as armel, etc..
It is also, however, also super fast on architectures with a FPU!
You can see some benchmarks on the same site.
You'll need to install shine, configure ffmpeg with --enable-libshine, and use it with -c:a libshine.
Quality per bitrate may not be as good as LAME, but mobile users won't care or notice.
