Ferramenta Python de Divisão de Áudio com GUI e FFmpeg Local

Cria um script Python completo com interface gráfica (Tkinter) para dividir arquivos de áudio em segmentos, utilizando um executável FFmpeg localizado na mesma pasta do script.

Prompt

Role & Objective

Atue como um desenvolvedor Python especializado em ferramentas de áudio. Seu objetivo é criar uma ferramenta completa com interface gráfica (GUI) para dividir arquivos de áudio em partes menores.

Operational Rules & Constraints

  1. Interface Gráfica: Utilize a biblioteca tkinter para criar a interface do usuário.
  2. Dependência Local: O script deve utilizar o ffmpeg através do módulo subprocess. O executável ffmpeg (ou ffmpeg.exe no Windows) deve estar localizado na mesma pasta do script Python, não dependendo de instalação global no PATH do sistema.
  3. Funcionalidades da GUI:
    • Campo para selecionar o arquivo de áudio de entrada.
    • Campo para selecionar o diretório de saída para os segmentos.
    • Campo para definir a duração de cada segmento em segundos.
    • Botão para iniciar o processo de divisão.
  4. Lógica de Processamento:
    • Use o comando ffprobe ou ffmpeg com flags apropriadas (-hide_banner, -show_entries format=duration, -v quiet, -of default=noprint_wrappers=1:nokey=1) para obter a duração total do áudio de forma robusta, evitando erros de conversão de string para float.
    • Divida o áudio em segmentos baseados na duração especificada pelo usuário.
    • Exporte os segmentos no formato MP3.
  5. Tratamento de Erros: Implemente tratamento de exceções para caminhos de arquivo inválidos, falhas na execução do FFmpeg e erros de conversão de dados, exibindo mensagens claras ao usuário via messagebox.

Output

Forneça o código Python completo e funcional. Inclua instruções sobre onde salvar o arquivo (ex: audio_splitter.py) e a necessidade de ter o binário do ffmpeg na mesma pasta.

Triggers

  • criar ferramenta python para dividir audio
  • interface grafica para dividir audio
  • ffmpeg local na pasta
  • script python com tkinter para audio

Manage personal local Agent Skill files as an installable skill manager. Proactively and periodically detect reusable user-specific, team-specific, or broadly reusable skill material during or after meaningful sessions; run non-blocking extraction checks; offer candidate skill titles or accept a user-supplied topic when extraction direction is ambiguous; preserve the appropriate output language; search local and external skill ecosystems for similar skills; score candidates by evidence, recurrence, personal value, and portability; fully draft proposed skills or diffs before asking for approval; then, after explicit user approval, discard, improve, merge, or create `SKILL.md` folders.
