+### 1. Embed Data into WAV Files
+
+```go
+func main() {
+    embedder := stegano.NewAudioEmbedHandler()
+
+    err := embedder.EmbedIntoWAVWithDepth("input.wav", "output.wav", []byte("Hello World"), stegano.LSB)

+        log.Fatalln(err)
+    }
+}

+### 2. Extract Data from WAV Files
+
+```go
+func main() {
+    extractor := stegano.NewAudioExtractHandler()
+
+    data, err := extractor.ExtractFromWAVWithDepth("embedded.wav", stegano.LSB)
+    if err != nil {
+        log.Fatalln(err)

+### 3. Embed at Specific Bit Depth
+
+```go
+func main() {
+    embedder := stegano.NewAudioEmbedHandler()
+
+    err := embedder.EmbedIntoWAVAtDepth("input.wav", "output.wav", []byte("Hello World"), 3)

+    }

+### 4. Extract from Specific Bit Depth
+
+```go
+func main() {
+    extractor := stegano.NewAudioExtractHandler()
+
+    data, err := extractor.ExtractFromWAVAtDepth("embedded.wav", 3)

 ## Advanced Options
 
 > You can use concurrency to speed up the embedding and extraction process. Use the `NewEmbedHandlerWithConcurrency` or `NewExtractHandlerWithConcurrency` functions to specify the number of goroutines to be used.
