I amplified an audio file using Audacity and subsequently increased its volume by a factor of 10 through the application of FFmpeg’s processing capabilities. When sharing the audio attachment with friends for review, I’ve found that those with older iPhones can still enjoy it without issue, albeit in limited numbers. In contrast, individuals with iPhone 14 models or later are often unable to hear my voice when playing the MP3 file.
On Apple devices with iOS 14 or later, my voice is barely audible in audio recordings due to the extremely low volume, rendering it nearly impossible to comprehend. Can you hear me now? Multiple phone-related issues are occurring successfully, with all audio settings fully displayed.
If you add background music to your audio using FFmpeg, those with iPhone 14 or later devices will primarily focus on the music rather than your voice, rendering your spoken content nearly inaudible.
What’s happening here is unclear.
That’s a tough one! After experimenting with Audacity, I successfully boosted the volume of an audio file on my Apple device. Although there’s been a noticeable increase, I still find myself struggling to fully hear myself, but some slight improvement is evident. Regardless of the audacity displayed in attempting to increase output, the labour expended and the efforts of ffmpeg under my command remain fruitless in their entirety?
Do you seek to govern certain parameters, such as frequency, and corresponding settings within the input when employing ffmpeg to amplify the volume? You can use the following ffmpeg command:
ffmpeg -i input.mp4 -c:v libx264 -crf 18 output.mp4
Thanks
I’m using the following FFmpeg command to increase the volume of my recorded audio: Uploaded correctly, please confirm that the.mp3 file has been successfully transferred.
The audio recording files stored in Audacity.
