🛠️ Bundled Tools

✅ Simple BGM Mixer

This is a tool to mix a voice file with a background music (BGM) file.

By this tool, you can make your podcast even more attractive by adding your favorite BGM to the audio generated by the Podcast Generator.

✨ Key Features

• ✨ The BGM will automatically loop to match the length of the voice (plus intro and outro).
• ✨ If the BGM is long, it will be cut to fit with the voice content.
• ✨ You can also finely adjust the durations and volume ratios of the intro and outro sections of the BGM before and after the voice, as well as the duration of the fade-in and fade-out.
• ✨ Outputs the mixed audio file in mp3 (160 kbps) or wav format in 44.1 kHz sample rate.

🎚️ Parameters

At a minimum, please specify an audio file, a BGM file, and output format.

• Voice File (voice_file)
  • The voice file to be mixed with the BGM.
  • You can use the Podcast Generator to generate the voice file.
• BGM File (bgm_file)
  • The background music file to be mixed with the voice file.
• Output Format (output_format)
  • The output format of the mixed audio file.
  • Supported formats are mp3 (160 kbps), wav.

I recommend running it once with the default values for all other parameters first.

If you want to fine-tune them, please refer to the diagram below.

The Duration is in milliseconds (ms). Configurable durations are as follows:

• A) BGM Intro Fade-in Duration (ms) (a_bgm_intro_fadein_ms), defaults to 100
• B) BGM Intro Play Duration (ms) (b_bgm_intro_play_ms), defaults to 5000
• C) BGM Intro Fade-out Duration (ms) (c_bgm_intro_fadeout_ms), defaults to 1000
• D) BGM Pre-Voice Delay Duration (ms) (d_bgm_pre_voice_delay_ms), defaults to 500
• E) BGM Post-Voice Delay Duration (ms) (e_bgm_post_voice_delay_ms), defaults to 1000
• F) BGM Outro Fade-in Duration (ms) (f_bgm_outro_fadein_ms), defaults to 1000
• G) BGM Outro Play Duration (ms) (g_bgm_outro_play_ms), defaults to 5000
• H) BGM Outro Fade-out Duration (ms) (h_bgm_outro_fadeout_ms), defaults to 5000

The Volume Ratio refers to the proportion of the volume of the original audio file, with 1.0 representing 100%. For example, 0.0 means 0%, 1.0 means 100%, and 2.0 means 200%.

• I) Voice Volume Ratio (i_voice_volume_ratio), defaults to 1.0
• J) BGM Intro Volume Ratio (j_bgm_intro_volume_ratio), defaults to 1.0
• K) BGM During Voice Volume Ratio (k_bgm_during_voice_volume_ratio), defaults to 0.2
• L) BGM Outro Volume Ratio (l_bgm_outro_volume_ratio), defaults to 1.0
• Z) Master Volume Ratio (z_master_volume_ratio), defaults to 1.0
