📌 概述

在当今数字化时代，音频录制工具已经成为内容创作者、会议记录者和音乐爱好者的必备工具。本文将详细介绍如何使用Python的PyQt6库开发一款功能全面、界面美观的桌面录音工具。这款工具不仅支持常规麦克风输入，还能录制系统音频，并提供了丰富的设置选项和精美的用户界面。

本项目的核心特点：

🎯 基于PyQt6的现代化UI设计
🎤 支持麦克风和系统音频录制
⏯️ 提供暂停/继续功能
⚙️ 可配置的音频质量和保存格式
📁 智能文件保存管理
🗄️ 系统托盘支持后台运行

🛠️ 功能详解

1. 核心录音功能

多设备支持：自动检测系统音频输入设备
高精度计时：毫秒级录音时长显示
状态管理：实时显示录制状态（录制中/暂停/停止）

2. 音频处理能力

支持多种采样率（44.1kHz/48kHz/96kHz）
可调位深度（16bit/24bit/32bit）
多种输出格式（WAV/MP3/FLAC/OGG）

3. 用户体验优化

系统托盘图标控制
快捷键支持（Ctrl+R开始，Ctrl+P暂停，Ctrl+S停止）
最小化到托盘选项
音频设备自动刷新

🖥️ 界面展示效果

主界面布局

在这里插入图片描述

界面采用分页设计，分为"录音"和"设置"两大板块：

录音页面：
- 大尺寸计时器显示
- 醒目的控制按钮
- 设备选择区域
设置页面：
- 保存路径配置
- 音频质量设置
- 其他偏好选项

状态指示系统

🟢 绿色：准备就绪
🔴 红色：正在录制
🟡 黄色：已暂停

🧩 软件实现步骤

1. 环境准备

pip install PyQt6 pyaudio

2. 项目结构设计

AudioRecorder/
│── main.py          # 程序入口
│── settings.ini     # 配置文件
│── recordings/      # 默认保存目录

3. 核心类架构

class AudioRecorder(QMainWindow):def __init__(self):# 初始化录音状态、UI和系统托盘passdef init_ui(self):# 创建主界面和分页passdef create_recording_tab(self):# 构建录音页面passdef create_settings_tab(self):# 构建设置页面pass

🔍 关键代码解析

1. 音频设备管理

def update_device_list(self):"""动态更新音频输入设备列表"""self.audio.terminate()self.audio = pyaudio.PyAudio()# 获取所有输入设备for i in range(self.audio.get_device_count()):device_info = self.audio.get_device_info_by_index(i)if device_info.get('maxInputChannels', 0) > 0:# 添加到下拉菜单pass

2. 录音控制逻辑

def start_recording(self):"""启动录音的核心逻辑"""self.stream = self.audio.open(format=self.format,channels=self.channels,rate=self.sample_rate,input=True,frames_per_buffer=self.chunk,input_device_index=device_index,stream_callback=self.audio_callback)self.timer.start(20)  # 50fps刷新

3. 音频数据回调

def audio_callback(self, in_data, frame_count, time_info, status):"""实时音频数据采集回调"""if self.is_recording and not self.is_paused:self.frames.append(in_data)return (in_data, pyaudio.paContinue)

4. 时间显示优化

def update_display_time(self):"""高精度时间显示（毫秒级）"""elapsed = (datetime.now().timestamp() - self.recording_start_time - self.paused_duration)# HTML格式化显示self.time_label.setText(f"<span style='font-size:28pt;'>{hours:02d}:{minutes:02d}:{seconds:02d}."f"<span style='font-size:20pt;'>{milliseconds:03d}</span></span>")

💾 文件保存机制

1. 智能路径管理

def save_recording(self, duration):"""处理文件保存逻辑"""save_dir = self.save_path_edit.text() or os.path.join(os.path.expanduser("~"), "Recordings")os.makedirs(save_dir, exist_ok=True)# 根据格式选择扩展名ext = "wav" if "WAV" in selected_format else "mp3"  # 其他格式类似

2. 临时文件处理

# 先保存为WAV再转换
temp_wav = os.path.join(save_dir, f"temp_recording.wav")
with wave.open(temp_wav, 'wb') as wf:wf.writeframes(b''.join(self.frames))# 格式转换处理（伪代码）
if ext != "wav":convert_audio(temp_wav, filename, ext)os.remove(temp_wav)

🚀 高级功能实现

1. 系统托盘集成

def init_system_tray(self):"""创建系统托盘图标和菜单"""self.tray_icon = QSystemTrayIcon(self)self.tray_menu = QMenu()# 添加菜单项actions = [("显示窗口", self.show_normal),("开始录制", self.start_recording),("退出", self.close)]# ... 添加到菜单

2. 设置持久化

def save_settings(self):"""使用QSettings保存配置"""self.settings = QSettings("AudioRecorder", "RecorderApp")self.settings.setValue("save_path", self.save_path_edit.text())self.settings.setValue("audio/format_index", self.format_combo.currentIndex())# ... 其他设置

3. 异常处理机制

try:self.stream = self.audio.open(...)
except Exception as e:QMessageBox.warning(self, "设备错误", f"无法打开音频流: {str(e)}")self.reset_recording_state()
